This isn’t coherent. Republicans seem extremely interested in controlling every facet of Americans’ lives.

What legislation are you living under that you can't "love who you want to love?" I live in a conservative county and can't hardly drive a mile without seeing a rainbow flag. I don't think any of them are in fear that the police are going to come knocking on their door talking to them about who they should love. Form a coherent point before trying to call out incoherence.
I'll hand it to you, "Trump is awful because he was a Democrat, and Democrats are de facto awful" is one I haven't seen before. That said, within my own anecdotal experience, "God Bless Trump" signs are pretty common in the Bible Belt, and that certainly is a sentiment born of authoritarian times.
