They've been doing this shit for years. Whatever is the hot topic activist social war issue of the day, they'll find some way to justify allowing a post on it, then ban anyone who complains that it is irrelevant.

It is typically a sign of poor leadership and a decline in quality of the online forum. Regardless of your position on polarizing political issues, once you allow them in a space that is ostensibly apolitical about something else entirely, you turn the space into a partisan political space. Activist types cannot have hobbies and must attempt to tie everything into the cause, so they will naturally try to do this for every space they infect, and without good leadership in a group they will eventually succeed. This like any infection kills the host, in this case the group, as once people realize it is infected they will leave and start new groups that don't suck.
