There's also a "Things that matter" social group which says:
General
Things That Matter
This is a place to discuss things that are important to us, but are too controversial for the general forums. Different opinions, as long as discussed in civil matter, are welcomed. If you are easily triggered, this may not be place to you. Yes, some things said here are controversial and challenging point of view is appreciatee as long as it is not in the area of hate speech. I will absolutelly NOT tolerate smear attacks against race, religion, nations, sexual orientation... so on. Supremacism of any kind is not welcomed here... there are other places on the internets for that.
