I understand that, and I've been a bitch on here too and I don't think people have to be nice 24/7.
I do think there is a difference between antagonizing someone and purposely trying to hurt someone for enjoyment. Now that I know what's going on I think Mitch, Chris, and Plunk are trying to get under her skin, even make her angry but I don't think they are trying to hurt her on purpose. That being said, getting enjoyment out of hurting someone else and being cruel to others is wrong, even online. In a few circumstances it can be justified, just ask ME when. haha kidding!
Sure, we all have it in us, but I try my best to master it. Just my opinion of course. I feel bad when I hurt people, even when they deserve it so it's in my best interest to refrain.
