A basic informal rule here has been to keep advertising or propaganda that is simply posted, off this site, whether it be for political reasons or to promote an album or concert. This is because this is a site for discussion, playful and serious. The exceptions have been for people who are genuinely involved in discussions, who are part of the give and take of what is going on, members, etc. Posting advertising or political news is not part of a discussion: it is pre-empting discussion.
Similarly, though it is not a rule on this site, but might make a reasonable rule for living, personal insults and racial slurs are bad manners -- manners being what one owes to another human being in reflecting their dignity -- because they are designed to assault and not consider.
As Mick points out, there is a thread for this discussion, which is being held (if occasionally barely) within reasonable temper. The sooner this thread is eliminated from this site the better off we will all be, including those who hold different views and look out from different windows.
yours, Peter T.
