To be fair, I don't think it's minorities that are asking for trigger warnings. They are groups with political agendas.

That is true. As many of you know there are an unusual number of transgender/sexual in the tech/geek communities and in my experience they get along with those of a conservative or christian bent and often have healthy non-rancorous debates with them. Perhaps they are supposed to be at war and some of them are but I don't see it. I think it helps a lot that people identify as geeks first so in a hackerspace it is assumed we're all in the same tribe, trying to be interesting people doing interesting things.
