First of all MacKaye was a member of hardcore band Minor Threat, a movement which ruined punk rock, not just by attracting a retarded new meathead audience, but also brough a really bad metal drum beat. MacKaye was responsible for starting the straight edge strain of mental illness, where a loser is too poor to buy drinks and too ugly to get laid, but claims they're "straight" edge as an excuse.
After leaving Minor Threat, MacKaye invented emo, dispite this nobody stopped him. All manner of faggots from those wigger dweebs the Beastie Boys to those unfunny retards NOFX to a whole manner of pretentious indie virgins look up to MacKaye as if he is some kind of great. Unfortunetly, as you can see from the rating on the other defintion, he has brainwashed his fans well.
Hey theres that Ian MacKaye guy, isn't he the guy who said drinking beer and fucking girls is wrong?
