The article I linked here is pretty typical; it's the comment below that I found offensive. Scroll down to the end of the article.

When you post as a member of any fraternity or sorority, you are theoretically representing Greeks in general. If you are going to "fight back" or respond to an anti-greek opinion piece, please least do so with some class. Proper grammar and a statement of argument (as in, "I disagree with what you wrote because .....") would help too. Otherwise, you are just feeding into the sterotypes.
