Also, we're talking about a political party here. This isn't a religion, or a family, or a culture, or an ethnicity, or anything like that. It's a name that's been applied to a group of people who tend to vote in the same way when it comes to national and local policy. I can completely understand an unwillingness to walk away from a religion - even in the face of extreme adversity, a la the Catholic abuse scandals - that's tied extremely close to someone's identity (or can be, for religious types). This is continually choosing to pay into the coffers of people who are actively campaigning on the right of men to abuse women, putting children in concentration camps, and destroying the economy and freedom of access to information because they have the same letter next to their name that you've always voted for - or because you actively agree with their stances. The only way I have of telling which it is, is if someone leaves the republican party, and refuses to support them. I can no longer assume that anyone who votes republican is just doing so out of convenience or because they've just always done it that way, because it's madness, and to give them a pass for it is to condone it myself. And they for damn sure better not try to come begging to me in 10 years when this is WWII levels bad and telling me that they couldn't see where it was leading and had no way to know that the republican party had turned rotten.
Edit: exchange they for you.
