Facebook is not a government entity, so there is by definition no freedom of speech violation.
They are absolutely free to censor whatever they feel, as they are not a public utility.
Really? Then why did the media attack the pub owner who didn't want to sell drinks to a gay couple? It's a private pub and they can serve or not serve whomever they want.
Facebook and Google are banning people who don't support their agenda. But at the same time ISIL can have their Facebook pages and other web pages, where they can publish pictures of beheaded people, or their manifestos. Nobody finds that interesting? No ban for criminals or terrorists, just to people who are against the agenda of a certain political party. Wow... some "freedom".
