You think the archtype of the edgy, rebelious youth is fictional? If you were too far removed from those groups of kids in high school, perhaps you should spend some time on 4chan.

>No. Banning Nazi content won't suddenly make it appealing to young people.

It absolutely does, because edginess is appealing to many teenagers/young adults. Not only that, but laws to this effect against blanket "hate speech" are regularly used by white supremacists and the like as evidence of, for example, Jewish people using laws to unfairly elevate themselves with the priveleges of a protected class while simultaneously suppressing thought that can lead to dissent.

Holocaust denial laws lead to increased suspicion with the justification that scepticism is banned to preserve a false narrative and prevent the lie from being discovered. It's easy to see how preposterous this is while the atrocity is relatively fresh in our collective consciousness, but what happens in 10, 20, 30 years when all survivors have been dead for some time and people rightly start to wonder why investigation of an event is illegal?

This is a weird form of puritanical censorship and the unintented consequences to society are far worse than any imagined benefits. You have no right to control thought in your image.

Edit: also, your hyperbolic mention of incest and necrophilia doesn't quite support your claims, as sexual arousal is quite strongly linked with taboo for many people, as evidenced by the wealth of voyeur, BDSM, and even incest pornography. It seems like these kinds of authoritarian proposals tend to come from sheltered minds.
