Welcome to the Sandbox

I belong to several Yahoo Womens Groups. They are an interesting place and even though we're all out of high school, they semi-regularly devolve into nasty little spats. Because of this I created my own group and invited a few people over from the other groups. I wanted a group with people who weren't easily offended and who I didn't have to censor myself in front of. Where I could be a cunt and a bitch and not feel judged. Well, one woman left recently on bad terms with some of the other members. I respected her decision and frankly it made it easier on me to not have to play referee as the group owner. Only now I think said woman has told some of the women I did not invite to my sandbox. What bothers me about this is the fact I was not being intentionally exclusionary, I invited the people who were more into my interests in an effort to make them feel safer because many of them had been lambasted at some point or another for their beliefs or lifestyles. I don't agree with them on everything, and they know this but we seem to be able to get along. What makes it even more maddening is when I first created the group I respected the woman who quit when she asked I not invite a certain person. I was trusting to her judgement and it ended up causing hurt feelings, though thankfully those have been talked past. But the people who I'm possibly hurting now? They are friends, I love talking to them but in a completely different context. No matter what I do I will upset people. I just hope they will come to understand that is not my intention.
