The one surefire thing about Medium is its open-door policy to writing.
The crux of the issue is that we, as flawed humans, often find ourselves saying one thing while acting in a completely different way. Proud, greedy, selfish. We just believe we're right and if you're of any use to me, I'll use you, and then I'll kick your ass.
I don't know why you want to create a group on Facebook, if it's obvious that you don't enjoy it?
However, writers need to be reading. Sometimes we complicate everything. I think it is easy to tell me what is bad in my writing and vice versa, that's the best way to support each other.
