How could anyone be this mean

I don't generally get into fights, I do try to de-escalate things as much as possible. My post in the other thread referred to that, as well as the fact that I stand 6'7" tall, and tip the scales at about 300 lbs, and when I have had to resort to fighting back, most opponents don't come back for more after the first shot.
Yes, I do agree with you, good advice to avoid confrontation, especially in today's world where you never know what weapons someone might have.
Except for you B I G guys, allowing the instigator to strike first can get you killed.
