> to be aggressive and yell crude language at people who are just trying to make a living in a manner or cultural context you don't understand or want to have anything to do with?

You're making a cultural assumption that the locals aren't rude to the hawkers. This is incorrect. The hawkers in fact are taking advantage of your unusual, culturally incorrect assumption that street hawkers shouldn't be treated aggressively, which is why tourists are their prefered market. How do you know the locals aren't quite rude or abrupt with the hawkers as well?
