Well, since as I pointed out, since a standard belief in God implies a belief in some sort of mathematical realism, denigrating any and all mathematical realism as "an infantile philosophy of little repute, believed in by lesser minds through the ages" implies denigrating a standard belief in God as "an infantile philosophy of little repute, believed in by lesser minds through the ages."
Just making sure that you know that you are insulting most people through what seems to be your militant atheism.
Note: I am not arguing nor I am going to argue against atheism, even your evident militant kind. Just know that are you insulting most people.

More dumping on a standard belief in God, I see.

It's mangled only in the mind of perhaps some militant atheists.
I'm only pointing out the obvious, which is that a standard belief in God implies some sort of mathematical realism.
If you deny this obvious fact, then perhaps you could explain how the former does not imply the latter, and so perhaps you could explain how this denigrating of mathematical realism is not denigrating a standard belief in God.

Hello? Mathematical realism is simply the notion that mathematical objects exist outside the human mind. Period. That means that if the standard belief in God holds, which includes the notion of God as Logos (literally, Logic), that any thought of any created being already is known by the Creator - and this holds in theism as well as pantheism, then some sort of mathematical realism holds. I just don't see why you don't see that if the God of scholastic theology of all the major religions exists, then some sort of mathematical realism holds. The operative word is "outside" or "beyond" the human mind. If such a God of scholastic theology is in any way "outside" or "beyond" the human mind, then some sort of mathematical realism holds. I repeat: I just don't see why you don't see this.
And before you start to make even more mistakes as to what so many people actually belief about what they worship, why don't you ask people who actually believe in an infinite God whether they think that this infinite God they worship is so dumb that this infinite God has never thought of irrational numbers - or is capable only of thinking of natural numbers or whatever.
And "pathetic "real numbers""?
Boy, it seems that since I've utterly destroyed your position on the merits, your "argument" has become nothing but throwing whatever insults you can think of towards what you so clearly hate.

This is true evidently only in the mind of some militant, bitter atheists.

Why don't you show us what this "much more adequate mathematics" would be?

I think someone needs to speak for himself on this "mindless obeisance" stuff and his evident worship of Wittgenstein.

So brainwashing is what you think of what you do to kids?

This is not true. You need to stick to the truth. And so we see that what I'm doing is necessary: Some of those who push the repeated addition agenda so while refusing to be up front about what they do.
In the naturals, repeated addition, is directly using the two given factors such that one of them repeatedly an addend under addition and the number of times it is such an addend is the other factor.
In non-integer rational number multiplication (a/b)(c/d) such that each factor is not an integer, we *cannot* do this above, and so we *must* redefine the algorithm, what we do - we *must* first break up one of the factors such that we obtain two new factors, one of the factors being the numerator of the broken up fraction, a[(c/(bd)), and only then can we talk of repeated addition of a given factor, this one being the one other than that former numerator in question.
In irrational number multiplication ab such that each factor is an irrational, repeated addition breaks down completely in terms of being able to preserve the original function a,b -> f(a,b), and we *must* redefine things so much that we now must replace it with some sort of approximation, a,b -> *approximately* f(a,b).

After the naturals, it's all a redefinition of what is done in the naturals, since recall that this is about math education and the progression from the naturals through the rationals to the reals and then Algebra I and beyond almost all of it based on the reals.

Not so, since again, this is about math education and the progression through the number systems in question.

No, again, since this is about math education, you have to redefine things for the students as they progress through the number systems in question.

And Kronecker as a denier was judged by history to be on this issue a crank.
Yes, even a great mind can be a crank on some issue.
Throughout history, many great minds' accomplishments were denied at the time by sometimes even other otherwise great minds, and these deniers all were in the end judged by history to be at least on those issues cranks.
It's too bad that you are throwing your lot in with the denying cranks of history.
I see a double standard: You deny and/or denigrate the math you dislike, math based on that which is not computable (almost all real numbers) and infinity and continua, but you turn around and have a problem with what you perceive others to be doing, which is the same to math you like, math based on that which is computable and finitude and the discrete.
(I say "perceive" because I don't think anyone is actually denying and/or denigrating the math in question you like. No, I'm not doing that. I'm just pointing out the limitations it has with respect to the math you don't like, math based on that which is not computable (almost all real numbers) and infinity and continua.)

I know, I know, there is all this that the term "existence" is not the proper term to use, and all that. This is why existentialist philosopher Paul Tillich phrased things the way he did, used the type of language he did, when speaking of God.
But still, we all know what is meant when it's said that God exists or does not exist. And so given that, I say that it's OK to use the easier to use "exist" language.
But if you want to be dogmatic about it, then that's you.

No - I don't make that mistake, not at all.
It's all based on one's personal ontological beliefs. If I was an atheist, then of course it is not the case that there must be some "existing object" in question and all that. As one who is not, that there is the "existing object" in question already there - in the mind of what I believe "exists" - is merely a natural consequence of my belief in such a one who has such a mind.
That is, you get it backwards: I do not say that there must be some "existing object" for there to be meaning. I say instead that since I believe that God "exists" and that this God has certain attributes with respect to knowing, then the "existing object" in question is already there in the mind of what I believe "exists". The latter is different than the former.
