There were some sporadic major bullying incidents at my high school, and yes, there's some major homophobia and verbal abuse. On the Day of Silence, there were people who were wearing the silence stickers and talking. Now that pissed me off. Either wear it, or don't. But don't pledge to be silent because "it's cool", and then talk. That's just disrespectful. But there was nothing really in the ballpark of McKinley.
I realize that McKinley is a fictional school, but there's bullying left and right, and nobody on the faculty does anything about it. Geez.
