People have grudges and dislike people for personal reasons. Get over it. If this were anyone else you wouldn't care. I know I wouldn't care that much if someone had a personal issue with anyone, especially if one of then appeared to have a drug issue.
But because Max Hall is a football player for a team you like, you do care. But all of a sudden we act as if anytime someone has a personal issue with anyone then they must not have legitimate feeling.
People have grudges, it's part of being human. Get over it.
