It's mainly making fun of the phenomena on Twitter about "being attracted to Himbos is pedophilia"/"dating someone a year younger than you is pedophilia"/etc. This is the logical endpoint of those garbage takes

I don't know if those people are TERFs or not but their views of endangering children are somehow even dumber

If you aren't asexual you're sexuality is deeply rooted in pedophilia and that is problematic 1/245
