It's one thing to stand up for yourself, it's another to down right treat people like shit. Before you post, think to yourself if these are the types of things you would say if the person were standing in front of you in a crowded room. If the answer is yes, then I don't want to be associated with you.
Bad example
Derp1 "You're fucking stupid."
Derp2 " Well I fucked your mom"

Good example
Derp1 "You're fucking stupid"
Derp2 "You may feel that way but that's you're opinion, which if isn't positive, would be better to keep to yourself."

Now let's all share icecream and talk about our feelings.
