Sex in hospitals, in schools, public places, public transport, in prision, violence, desperation, power relation, aliens?, most Japanese/animated porn is about non-consensual sex. A lot of this is illegal and most of it could be misinterpreted and lead to real life misunderstandings. At this level 80% of porn could be banned.

Two consensual adults or cartoons acting something illegal. And in UK porn is banned for underage already... So it seems problematic that they could just as easily justify to ban any book or video that depict illegal things
