Y'know, I think this bears repeating.

I did not at any point say that it shouldn't be allowed.

I'm saying it's RUDE. And I'm saying that, whatever the original motives, a lot of the people are participating not out of any Brave Devotion To Principle, but because it's a way to be an asshole to an out-group while claiming high motives.

And I'm not going to be cowed into suppressing my protest just because of peer pressure from the cool kids.
