@thesquirrelfish Child porn is obviously wrong on so many levels and needs to be stopped and obviously we agree that it is harmful to view such imagery so we completely agree that it should not be allowed to exist anywhere regardless of ones views of free speech.
But if you think that merely seeing an ideology is harmful to thinking adults then I would find that a very paternalistic mindset. I have studied nazi ideology in various university settings, listened to lectures about the psychology behind it and even read excerpts of Mein Kampf for similar purposes; i probably know the ideology more thoroughly than most actual neo-nazis and yet I somehow find myself still in disagreement with everything it stands for and am still disgusted by people who espouse even portions of its tenets. Did any of that study harm me? No. Would seeing some random person online foolishly supporting those doctrines harm me? No. Do ignorant people exist who will fall for these foolish ideas? Yes there are, but the solution to this is education, not just trying to make them even more ignorant which is itself a supremacist idea.
