BS way to attack his candidacy? Again - we are talking about Trump's GOP. They will absolutely attack the ever loving fuck out of him on both this and his lack of experience, and those attacks will land with the religiously inclined.
I absolutely do want progress. The people i've voted for in my adult life alone support that. But I grew up in urban hispanic and black communities, and I know how religious, democratic voters in rural states feel on this topic. In fact, there is a strong chance that there are pockets of voters who don't even know he's gay - it certainly took some Iowan voters by surprise. I've already overheard people in my orbit who have voted D for as long as I can remember (in a blue state no less!) say they wouldn't vote for Pete because hes gay.
Honestly, I feel like in a lot of left-leaning circles like here, we simply won't talk about the General Election optics of his sexuality cause we, of course, want to believe we live in a country that would absolutely vote for someone regardless of race or gender or sexuality. I want that to be the America I live in. But, unfortunately, we don't. And again - all the other candidates have shit they'll be hammered on, some more than others. But this particular issue is an untested one, and he's already in terrible trouble with latin & hispanic voters as is.
