And its not dogma.
But you have just asked what "w" and "m" are supposed to mean, remember? That's why I call you (and co., don't take it personally as it isn't) parrots etc.: because you are just right, whatever kind of bollocks you might say, in the end you are still right. By dogma, and the guns.

Indeed, to be precise, you and co. excel in not even being wrong.

The real numbers are a subset of the surreals. But I had said that already. Of course they are countable: there just is no such thing as a number that is not a number: a number is all we can do with it seriously (you won't get this, but never mind).
Well, maybe it's not dogma, it's just that you cannot read... But no, I am not optimistic about anybody's intellectual honesty around here: except maybe for Prof. Magidin, who at least shows some good math.
