I've never watched Glee so wasn't really a fan of his, but this has made me feel incredibly sad. For him, for Lea, for his family and friends. Regardless of how he died (I read that the autopsy results will be announced early this week?) he has left behind people that will miss him and need to grieve for him. I hate that some people use something sad like this for their own gain, or to big up another sad event.
All death is sad to someone but it is logical that a celebrity death gets more attention than the death of a non-celebrity. I saw a great quote on Twitter which was something along the lines of "Don't let anyone tell you you can't feel sad about what you feel sad about" and I agree.
