I have long hair because I think haircuts are a communist plot to... fuck, I don't even know anymore, they're just so stupid they could only have come from communism.
You have some jackass standing behind you with
SHARP OBJECTS NEAR YOUR HEAD, MOTHERFUCKER!
and everyone you know has been pushing you to do it since you were a baby. Exactly what about that *doesn't* set alarms off?
It is also useful as moron repellent. When you're six feet tall, bearded, long-haired, and growling at people who walk too close to you, everyone leaves you the fuck alone. If people ask you why you have such long hair, "strangling" is as quick and efficient an answer as possible. Even if you aren't interested in terrifying strangers with your presence, you can cut down on small talk with hoity-toity cunts and smarmy jackasses in suits by insisting that they're insane for trusting strangers with
SHARP OBJECTS NEAR YOUR HEAD, MOTHERFUCKER!
for no good reason.
I scare people for a living (specifically, teaching college mathematics) and long hair helps tremendously - even when dealing with students who have long hair, as they don't expect their teachers to be 20-year-old metalheads who worship themselves. Haircuts are only considered 'normal' today because they were 'normal' yesterday - there is no good reason for considering 'normal' the act of arranging for others to put
SHARP OBJECTS NEAR YOUR HEAD, MOTHERFUCKER!
and it's time that stupid bullshit stopped.
Finally, pencils, small knives, and lightweight electronics can be stored easily in long hair. If you don't see how this can be a great reason to not put
SHARP OBJECTS NEAR YOUR HEAD, MOTHERFUCKER!
just try it for a while.
