Yes. We're all racist in our own way. Now, that doesn't mean being racist is negative, it just have a negative connotation when people bring it up.
We behave accordingly to social constructs and this is composed of how we are brought up and our beliefs. For instance, I interact differently with different kinds of people. If I see someone wearing a turban and religious dresses, I would have a filter and try my best to not juggle the f word in front of them (for a sign of respect because I am assuming they wouldn't like that). But of course, this is flawed because I am behaving with my assumptions that could be utterly wrong. But isn't that how we behave with other people? We assume things about them and we act according to what we think is best socially?
