Of course they exist, Bruce Jenner is always trying to maintain his relevance politically, there’s definitely quite a few other “celebrity” types who are also outspoken gay Republicans, sorry just jot sure why you added that caveat.

Those Republicans that you know are quite naive about the threat coming for them, and it’s not like the Christian right hasn’t been systematically taking over the Republican party for decades, my go to for this topic is Barry Goldwater’s famous quote:

Mark my word, if and when these preachers get control of the [Republican] party, and they’re sure trying to do so, it’s going to be a terrible damn problem. Frankly, these people frighten me. Politics and governing demand compromise. But these Christians believe they are acting in the name of God, so they can’t and won’t compromise. I know, I’ve tried to deal with them.

As well as this quote:

I’m frankly sick and tired of the political preachers across this country telling me as a citizen that if I want to be a moral person, I must believe in “A,” “B,” “C” and “D.” Just who do they think they are?
