Have you considered that the reason why most people are okay with Facebook not punishing president Trump is because many people agree with him? Have you considered that -- facebook having more active users than twitter -- that facebook is more representative of the United states than your feelings?
Twitter is known to be mainly popular among the media, who -- shock and surprise -- don't like trump and lean liberal. Facebook is popular amongst the rest of us. Is it possible in your worldview that other people may not think like you?
