The reason you should speak up for Trans people is simple: because you should. Not just because they'll come for you, too, eventually, but because we should care about Trans folks, full stop.
@kimlockhartga In fact, this has me thinking. We should be arguing that they just need to be the better humans they know they should be instead of framing it as everybody coming after each other. I mean, I'm afraid I find it hard to believe it would stem the hate-mongers but... it's got me thinking.
