We say that this site toughens us up. (IIRC). I think we should have a thread for, general advice to help people who don't find it easy to cope with attacks, people disagreeing with them etc. I have come a long way since my immature early days on WP, and I would like to share my own coping tactics, and hear others.
One of mine is just to sit back and realize that all the most intelligent, important people get attacked and disagreed with the most. Al great scientists, world leaders, politicians etc.
Another is just to not post immedialtly, but type it out, then come back to it and think before posting it.
(I don't nessacarily follow these rules )
