EXACTLY!
If they weren't scared of us...why would they scurry to the other side of the street to avoid passing us on the sidewalk?
If they weren't scared of us...why would they clutch their purses, bags, etc?
White women are afraid we're gonna mug em or rape em (even though the majority of rapes are committed by white men)...white men think we're going to rob em or mug em...meanwhile a white man is robbing them blind and rapin their wallets.
I would never do either of those 2 things, I just think some people over react more so then some other people. I honestly think the people that over react end up putting their selves in a bad spot both in that situation and in life in general. You cant judge someone from 50ft away, you will lose out on meeting some good people, Just because you are white, wearing a sweater vest and some gay ass pointy shoes don't make you a good person. Some of the biggest pieces of shyt I know are white with 800 credit scores.
Example, I was born and raised in a bad neighborhood. 90% of my friends were/are black, I chilled everywhere and it was nothing, its an every day thing. As I got older I became friends with coworkers and randoms that live and nicer spots and I definitely see what your talking about, but I honestly think doing stuff like that makes the situation so much worse. If someone is even thinking about jumping you, if you stay on your path its a 50/50 shot depending how he made his mind up on what hes going to do. If you go out of your way to avoid him... he knows he got you and you're an easy target at that point.
I would hang out with some of these guys in their weak ass spots, and a group of 10 people would be scared if an argument broke out in a bar, I'm like wtf? I made the mistake of taking 2 coworkers to 1 of my spots and that's when i realized I guess I was raised much differently then they all were. I'm there drinking and going crazy with people having fun, i turn around they were in the corner against the wall like they were working security scared shyt. So I sent some girls over to relax them a bit, and both girls walked back over asking whats up with my friends they are weird. I walked over to them and could tell they were not comfortable, i brought them home and went back
I got some funny stories about bringing some people out in a different type of environment they are used to. Some are hilarious (rich German boss for my friends company came from Germany, we took him to this grimy spot we chill at, and dude balled out, everyone loved him, shyt was hilarious) another short of of a kid at my job who would always talk about fighting, took him out 1 night, he got so scared he called for a ride and pretended that "his friend was in the area and is picking him up"

So to sum it up I don't think blacks in general are scared of whites, and I don't think in general whites are not scared of blacks. It's just different on a person by person basis.
