Straight edgers are just another group of entitlement cows who seem to wear this label out on their sleeve, go out of their way to tell you they are straight edge, and expect some sort of special treatment because of it.
Just add them to the list along with mother's who think that just because they have a kid the world owes them something, gay guys who are "loud and proud", vegans, religious folk who want to "save" us non-believers, etc. etc. etc.
