Great detailed post by dwise1, glad someone else (and of course, he is not the only one, and with this I praise all) can step up and defend mathematics, which is evidently under attack by a few of the, to put it mildly, unenlightened.
What will they attack next? Obviously no form of knowledge or virtue is off the table. That is why sometimes, I just can't bear to look for a few days.
