@Roberta,
There's probably few people who have traded more acid comments and barbs than Finn and I, here on A2K; at least, non-trolly people. But I have to tell ya two things about it: first, I don't take it personally and I doubt he does either; and second, people only show such emotion towards others who are worth talking to.
People who aren't worth discussing issues with are simply ignored. The fact that someone would even care enough to GET upset is a mark of respect in itself.
As to the larger question - how well do you think we know each other? - I feel that I know some people very well, and I feel that through my opinions written here, that many here (who have bothered to read my posts) know me and my true opinions better than almost everyone in my regular life. There's just a freedom to be yourself, here.
I have heard, though, that some people have a difficult time feeling like they know someone unless they have seen a picture of them. Seeing IS believing, as they say. So here's a pic of me:
... on my wedding day, happiest day of my life, in Maui, Hawaii.
