Like they say, the issue is not with the depiction of something that actually happens in the real world. The issue is with what surrounds the depiction. Glee has this tendency to present hate speech and stereotypes without any commentary, usually in a positive light, and then it acts like it is doing something superprogressive by doing so. Ryan Murphy seems to have missed the memo that it is possible to depict oppression in a way that adds to the body of criticism surrounding that oppression, as opposed to just casually reinforcing it.
