As much as it pains me to say this Trump may be the least terrible of the two as the damage Pence would do to the LGBT community (I don't think camps are a possibility) would last a generation and would embolden those with similar views to publicly act on those prejudices without fear of criminal action.
I don't think Trump cares one way or the other about the issue as it doesn't involve him personally.
I have a feeling Pence would also be terrible for atheism and science in the US as many Americans seem to have this odd terror about atheism taking over just because some atheist somewhere wants a bench or a sign promoting atheism. I remember fox news went mental when London Buses had slogans saying "There is no God" (there were signs after saying "There is a god") as if just seeing a bloody sign would make Christians think "hang on that bus has a point, screw religion I'm becoming a militant atheist and am going to stand outside the nearest church and gently cajole people as they leave. That'll show-em!".
You've got to be really, really odd to take theological advice from a bloody bus
.
I am surprised Trump hasn't actually declared war on Christmas as Fox news love banging on about how Christmas is being destroyed (seriously, the guy needs to work in a shop over Christmas and then tell me Christmas is being destroyed) by someone having the audacity to say Happy Holidays. He gets all his other political ideas from Fox so why not just go full on and let them declare War on Christmas live on Fox and Friends and just mass arrest people who aren't Christmasy enough.
