Ya that's not what you're mad at.
You're making an all-encompassing declarative statement insinuating that fundamentalist Christians are marrying off their children to grown pedophiles. That is a hateful generalization supported by literally no actual facts. You're doing the exact same thing as someone claiming that drag queens, as a group, are sexualizing children.
And before you put your thumbs to the screen, yes, I realize there have been isolated incidents of this happening. Crimes happen across the board, and they deserve to be investigated and punished by the law. That's not the issue here. The issue is that you're using an isolated subject to justify what is ultimately a hateful generalization about a particular group of people. That's prejudice and hateful, regardless of which group you're directing it toward.
And your link is totally irrelevant in this case. It is obvious that you did not catch on to what I was saying.
