When I'm arguing with you on here, unless you're being a bigot and sometimes even then if I think you're just misinformed, I'm arguing in good faith. I want to reach consensus. I'm giving you the credit that you might have something interesting to say, or to challenge my point of view.
If you just insist on feeding me hostility, I'm going to give you a chance, and then I'm going to block you and hide your thread.
