I'm glad we've reached the point, as a society, where we can compare people's sexualities to trivial decisions about outward appearance during a time of youthful rebellion!
Careful now, I'm not comparing sexuality to outward appearance; I'm comparing
prejudice against sexuality to
prejudice against appearance. It's the same prejudice -- he's different to us, he must be weird, I'll steer clear of him. "I want to dine with people who are like me" -- i.e. whites, non-gays, christians, etc. The wellspring of prejudice is the same in all instances, regardless of what is being prejudiced aganist.
It says they go out of their way to attract attention, even if it's negative.
Uhh, it couldn't be because they
like pink hair, could it? You don't think you're, uhh, pre-judging people, do you?
It also says they probably don't have a job that pays taxes and that they aren't especially interested in getting one.
Quite enough for starters.
Erm, you do realise the circularity of this whole argument... "He can't get a job because he has pink hair. He has pink hair because he doesn't care about getting a job."
It's a self-fulfilling prophecy: People call pink-haired people weird, so fewer people dye their hair pink, thus making pink-haired people stand out even more and look even less normal.
Maybe if people weren't so prejudiced against people with pink hair, more people would be willing to have pink hair, so that accountants and engineers would also start dying their hair pink.
All these prejudices have a common source: automatic and irrational dislike of people who are different. I'm generally opposed to anything that is irrational and stupid.
