But the above statement of the good question leads me to put a question to Haim:
How come you do not jeer at Bob Hansen (as you jeered at Tom at the thread "Elements of Algebra") for the egregious errors RH keeps on making in the writing (and, indeed, thinking) that he puts up here? (As exemplified by "we're" for "were" above. I personally would accept the above as a mere typo - but I do need to ask you why you went out of your way to humiliate Tom.
