...assuming the asian is better at math rhymes along racist attributes.

Depends on what asian you are talking about: the asian man in the example or the asian in general? And better than who exactly? If someone was to accept scientific data (if there was such available) showing that people with Asian descent tend in average to be better at math (or have a higher IQ) than people made up of different biological backgrounds, that would make that person racist? Sorry for the hypothetical question, because I have not read enough about the topic to have a definitive answer in regards to the correlation between physical and psychological traits, but all I'm trying to point here, whether it would be for anthropometric, cultural reasons or else, is that if there was revealed to be something about ''the asian is better at math'', I wouldn't label this along racist attributes because of the appreciation (better, more, less or not than) that would happen in this case to reflect reality about only one single trait. I believe what we are talking about here is racialism not racism, even if some dictionnaries seem to see the two words as interchangeable (erasing as a result the former à la 1984?), I can't help but to make a distinction between the ideas of ''we are different as groups'' (racialism) and ''we are superior as a group'' (racism).
