It's bait. Take a vague dataset, and draw overgeneralized conclusions from it to play into people's biases and hostilities.

And people LOVE it. They want to believe that republicans are all evil transphobes who are sitting around masturbating at trans porn all day, because it makes them feel good about themselves to setup these strawmen compare themselves too.

The truth of course, is far more nuanced and complex, but people don't want to learn. They want to hate-masturbate and ego-stroke.

Oh and let's not forget, all religion is bad and evil and hates sex!
