How about you ban school uniforms from school. The fight is lost, let the kids wear cargo-pants if they want to.

I don't know what to say about that. I feel kinda conflicted. On one hand sexualising school kids is, to my mind, abhorrent. But banning certain clothing in porn seems like overreach and consenting adults should be able to dress as they like. Dunno.

Are we to believe these 14 and 15 year old girls watched pornography featuring adults dressed in school uniforms, and then decided it is abhorrant and should be banned?

This isn't their agenda, they're being used to echo somebody else's beliefs, likely an adult with a duty of care to them, which itself is concerning.

There's something very noncy about finding women dressed as schoolgirls attractive.

Know what, this is reasonable. I find the whole "schoolgirl/boy" thing in porn concerning even if all involved are 18+.
