Sorry you feel that way.
I suggest to you that, when thinking about race, you might think about people like Justice Clarence Thomas, Secretary of State Condoleeza Rice, former Secretary of State and General Colin Powell, economist Walter Williams, columnist Armstrong Williams, not to mention millions more less famous but equally honorable black folks.
I live in a racially mixed neighborhood, including a black Baptist preacher and his extended family, with zero problems.
In fact, the only time anybody in the neighborhood was mugged, it was by a couple of young Asian men. I kid you not.
I know... there are exceptions to the rule, and that is great.
I too have seen Asian gangs who can be extremely vicious... but they don't seem to go out of their way to be aggressive and confrontational with everyone who crosses their path.
Heck, there is a white trash kid on my block who likes to come tearing up our cul-de-sac in excess of 40mph with kids playing... I'd LOVE the chance to put a 7.62mm round through his engine block.
But again, exceptions don't prove or disprove a rule. Hard facts and statistics do.
Also, this really is not a matter of me 'feeling' a certain way. I am a linear thinker, quite logical. I assess relative danger based upon past experience and probabilities, that's all. Right now... It just ain't looking too good for the brothers. I sincerely hope more of them start looking to the positive role models you have cited instead of the thug/gangster/rapper sect.
