One of the things that drives me nuts is when people make a huge, sweeping statement among a group of people.

The one that irritates me that I see the most is "We're all gay here :D" and I'm just like. I:

If it's a small group and I'm just being overlooked it's whatever, I'll get over it. But when there's plenty of bi/ace/pan folk there too it's like, yeah gimme a break.

Speak for yourself and only yourself, folks. Trying to erase people who are different than you so you can be more comfortable is really shitty.
