Are you sure about that? So if I hosted a website that shows your name and address, you could do nothing to make me take it down because I’m not an organisation or company?
Sure, or racist stuff. But antisemitism, racism and sexism are unfortunately not just limited to nazis, there are plenty of other people who say anti semitic, racist, homophobic and sexist stuff.
