Blare picks on him for a reason… he doesn’t really represent any sizeable movement.
Anyway, I know what he’s saying sounds like a contradiction but it’s just poorly worded.
What he’s saying is “If you were attracted to someone who is trans, and would date them if they were an actual woman, but won’t only because they’re trans” that’s discrimination. You’d have to basically WANT to date this trans person and reason “Gosh if only Sam had been born Samantha and not Samuel, I totally would!”.
While there’s still a fair case to be made against even that very specific and limited definition of bigotry, it’s also something with fairly limited application.
What he’s not saying is “Though Riley Dennis looks like a man with long hair and some mascara, if you don’t find
him her attractive, you’re a bigot”. Even though that seems to be how nearly everyone interpreted it.
