Are there any political issues, such as abortion or capital punishment, that are so fundamental to your core values that you could not respect and/or trust someone who held a contrary view?
It's really only that way with same-sex marriage and/or gayness. Sometimes abortion, but abortion is a lot more of a grey area though because the labels are all mixed up nowadays and a lot of people aren't informed as to what pro-choice actually entails.
But yeah. If you're anti-gay I pretty much don't like you. Sorry.
