Context is also important, I have no problems with displaying footage form Nazi experiments on concentration camp prisoners for educational purposes I could however agree that it is ok to block the same footage when it’s shared by neo-Nazis or white supremacist groups on Facebook for lolz and pride.

I also think that this is a stupid argument this footage is not illegal and can be considered by many newsworthy hence should be protected at least in some narrow context.

Child pornography on the other hand is illegal. Broadcasting or displaying child pornography has no newsworthy or any other value in any context other than the pornographic one.
