Well the answer I'd like is "you should tell this person this and this, and it should be enough to let him understand your position and cricize you less for it". What I wouldn't like to hear is "don't talk with that persona anymore, you're compromised", because finding new communities to try to get into and then having to leave them because people can't stand you (or even worse where you can stay but you can't talk to people you wish you could) is... well, stressful.
I guess anything in between would be an ok response?
