The latter part of your last sentence is false. Every group in the US has a very vocal racist minority. You just think that because those are the ones that yell their racism the loudest out of other black people. You would think the same about Southern Whites if you only listened to racist Rednecks and not regular Rednecks.
But with Han Chinese they have always had a superiority complex when it came to people of other races.
America does have a racism problem, and it's not White on Black like your media likes to constantly proclaim -- it's Black on White and Black on Black.
You can say it's just a "minority being vocal", but the mask has basically slipped in the last few years, especially with BLM's higher-ups, and when you see the same rhetoric over and over from different people, across different platforms,
even in everyday conversation, this isn't a minority but representations of a trend in your society.
It's getting so bad that when Whites in America are being b
loody murdered by Blacks, no-one in MSM is reporting it so these things aren't picked up on by the general public.
To add to this? Your own government and other institutions are essentially covering for this shit by refusing to have statistics published (especially relating to crime) and the like, and MSM doesn't report on such incidents because a) it doesn't bring in the dollars and b) goes against The Message.
Look up Alexandria Borys. She was a White mother who was recently murdered by a Black woman over a Walmart parking dispute on Valentine's Day, while her children were in the car behind her. Yet because she was White? It didn't make any major news network. Shit like this is happening all over the US, but if the ethnicities were reversed? It'd be all over MSM like flies on shit.
When a Black person stays in school, gets an education/job, and contributes to society? They're turned on by their kith and kin. They're called fucking Oreos because they're "like White people".
Date a White woman or man? You get turned on -- Black women are
especially bitter if a Black man dates a White woman.
People in predominantly Black areas report harassment, even goddamn teenagers,
because they're White. This is kids being racist towards other kids, and that behavior is usually learnt at home from their parents.
Back when I was young I thought only a few White people weren't racist. Because back in the 70s the bulk I ran into were racists. But as I grew up and traveled more I realized that was not true and it was just that small group of people. They same thing is with you experience. You will see what I mean when you have lived as long and traveled as much as me.
Sorry bro, but things have changed since your time traveling: Blacks in America, on the whole, are now disgustingly racist towards Whites and fellow Blacks they think are "traitors". Or perhaps the rot is just becoming more surfaced now, I dunno.
You can call it all "isolated incidents" or a "vocal minority", and the Black people you've encountered (especially in the various Services) may have all been upstanding citizens and people, but this shit is pretty much endemic in American society now.
America is racially divided, and it's mostly Blacks throwing petrol on the fire -- not Whites (I say 'mostly' because there will always be shit-heel Whites out there doing the same, but this isn't the 1940's/1950's any more).
You need to fix this shit or you're going to be looking at current South Africa as your future. smh
