Your thoughts about this are absolutely noble. Remember though that you are not responsible for the other people in the chat rooms. You must take care of yourself first.
My private chats aren't to leave anyone out but to help me or someone else who doesn't want to upset the entire chat. There are sometimes things a person just can't say to a whole room full of people, but they can manage sharing it with just one or maybe two people.
I was terribly hurt by something that happened in chat recently. Looking back, it was no one's fault, it just was one of those things. There was no harm meant, so I had to shake it off.
If people leave unsatisfied, maybe they'll speak up the next time. It is up to them to speak their needs. They'll get there.
We all love having you there. Please don't worry. All is well.
Hugs,
Jan
