NEVER post angry. If you are angry, you will say things you should not
This is my golden rule. I'll usually only post a reply if I'm "stewing" about something for a while I find it very interesting that it's the same people that do it over and over again. I also find it interesting the some are applauded for being "to the point" or "frank" or "truthful". There is such a thing as tact. There is no need to be rude. Reread your post out loud to yourself and consider how it comes across. If you have a "helpful" suggestion to a newbie, send them a polite note privately. No need to cause anyone embarrassment.
If you want to fight take it private 'cause no one is interested.
