(Quote:) Yiannopoulos, a 32-year-old right-wing provocateur, is ...  a self-proclaimed internet troll whose comments have been criticized as racist, misogynist, anti-Muslim and white supremacist. He was banned from Twitter after leading a harassment campaign against Ghostbusters actress Leslie Jones.

Not that I support rioting and rock throwing - he simply should never have been invited.
