I agree about the filthy way that cobra was talking on the boards. It is not needed and like cobra said, it is immature (he really said kids are talking that way when you are not looking). He may be right, but I doubt you can assign that behavior generally to that age group.
I do think it is not really "disrespecting" any athlete when you take a side on who wins a contest. It is just sports talk and as long as it is not personal, no big deal to me.
