Facebook Wouldn’t Let Me Post Facts About Bernie Sanders – Censorship

I tried posting this meme yesterday on Facebook and it wouldn’t let me. Besides “Bomber Bernie”, it just lists his votes on defense related matters. Is this happening to people who post facts about Hillary by Bernie supporters too? Facebook is already contributing to the downfall of our electoral process by showing people just what they like, thus keeping them insulated from any opinions that might run counter to their own. Now they are censoring factual information, why?
