The old love/hate thing. I get it.
We have to learn not to take it all too seriously. If you get too heated, step back and take a break.
Even (God forbid),(clearing throat now)it makes you get accused of being a loser and a wimp.
My rule of thumb [actually, rule of fingers typing on the keyboard] most times is to attack the post, rather than the poster.
Many, attack the poster because they are short on ammo [facts] to attack the post. And that puts them in the same class as Alinsky, Clinton [politics of personal destruction/crash and burn], etc.
