Just saying, even among republican voters, nobody really cares about same sex marriage anymore in the US. Yes, there are definitely still people that are against this, but the majority are just cranky old people. As someone that grew up in the 2000's in a red and rural area, nobody really cares except for the old people and the aggressively religious. I used to work at a dive bar in the middle of nowhere and one of my coworkers was openly gay and nobody gave a shit. If anything, that man got tipped higher than a lot of the female servers most nights.
I guess what I'm trying to say is that no matter how bigoted and awful republican voters seem online, I'm pretty sure the majority do not even consider this a problem. I'm not saying this should absolve them of fucking over the country with their votes, just that this might be something that will piss them off too. Most of the republican voters in my home town aren't even religious. They built one of those giant churches in the middle of town awhile back and every time I visit my parents that place is basically abandoned.
But what can I say, I absolutely love it when they piss of their own base as they try to appeal to the extreme. Every day they lose more and eventually they won't have anyone left. Probably won't happen for a few decades when I myself am an old man, but hey, I gotta at least try to be optimistic.
