Not speaking for the previous poster, but in any case, that severity is not easy to measure. I have the understanding that in the U.S., there is institutional and deliberate discrimination against Asian Americans. For instance, in the admissions to Ivy League colleges. A random article about the issue:

"...students who self-identified as Asian would need about 140 points more on the SAT than their white peers would need to get into elite, private schools. That number jumped to 320 and 450 when Asians were compared to Hispanic and African-American students, respectively."
