@cford I think it's mostly that many a) men, and b) people in tech do honestly believe that they have a more reasonable, more logical, more correct view of whatever is being discussed than the layman, and sometimes even than people with somehow less knowledge on the subject (or at least they think the other party has less knowledge, often without bothering to check). The urge to correct somebody may stem either from an honest desire to teach them, or from an egotistical desire to demonstrate one's own superiority. Combine the two, and men in tech are, in some ways, indeed the worst.
Please note that I am not excusing anybody's behavior; people MUST learn to question their own PoV, and people absolutely MUST learn to treat others as human beings.
And yes, I do say all of this with a full realization that I have behaved like the man in tech that I am many times, and sometimes do it still.
