I'm trying real hard to be a shepherd. Blacks do not all think alike. Whites don't think alike. The matter of fact is that some blacks hate Asians and some don't. And then others don't even care.
Gross generalization is the sign of immaturity.
I will relate my own experience. I came to the states in the '60s when there was a social turmoil due to the war in vietnam and civil rights movement. During that struggle, blacks generally looked upon us, Asians, as their allies. My observation is that the opening of the immigration flood gate, circa 1970, changed all this. The new immigrants did not know the struggles that went thru.
