I think we we can agree is that Parker's not necessarily racist but the depiction on the page is.
it's a combination of things with both art and writing contributing to the deeply unpleasant stereotype.
But that doesn't necessarily make Parker racist in the same way the AIEEEE Tigra beating in New Avengers didn't necessarily make Bendis misogynistic. It might not be racism but it sure looks like it at first glance.
