I've been on OKC for about 8 years, been poly on there, met poly girls there, had poly friends there, never once heard of anyone getting harassed for polyitude.
I'm not saying it didn't happen... but it might be kind of like saying "planes aren't safe, I had a friend that was in a plane crash."
Sorry if it came off as me saying that people in poly relationships aren't at all welcome on OKC, just that it's not universally welcoming.
I'd imagine how welcoming people are to others in poly relationships largely depends on where you are. People in El Paso, TX (where my friend and I live) are likely less open to that sort of thing than people elsewhere.
Oh yeah? I've only ever ...heard otherwise, and I'm pretty sure that several of the founders are poly as well. I could be remembering that incorrectly...
Not true for OKC. Very poly friendly.
