Q1: Is Heavy Metal a subculture that is esoteric to all but those who love it.
Yes. Most people wouldn't really understand it, not until they've listened to it for a bit anyway. Also there's a certain amount of inherent stereotyping going on. Up until you've spent time with people who listen to Darkthrone, dress all in black, and hail satan you would tend to reduce them to the mental image of said. But once you've hung out, and heard them interrupt your debate on whether or not Christianity had a negative sum effect on history with whether or not they should ask the goth chick at the next lunch table out, and bitching about their math homework they're a bit less intimidating.

Q2: Would it be possible to "teach one to like heavy metal" who originally had a serious dislike for it. For example. Can one take my mom, who likes The Beatles, and slowly introduce her into metal and teach her to, at one point, like a band such as Venom or Mayhem even, after years of indoctrination and work. (This is hypothetical. No "If she doesn't like it, why would you want to force her to?) kind of answers.
You could teach someone to "appreciate" Metal (i.e. recognize a good guitar solo, or a strong riff, or a really great death growl). But you couldn't make them like it.
On the other hand if you think someone might like metal, you should introduce them to something lighter and pop-ier like the newer Dragonforce stuff. Then slowly, as they get calloused to things like overblown distorted guitars, not having a clue what the hell they're saying, ridiculous speeds, and talent; you can give them stronger and better stuff until they are weened off of pop music.

Q3:Do people have a predisposed personal appeal to some subjects, and a retraction to others that is natural and unchangeable?
I don't think there's a "musical taste" gene that's inherent and unrelated to other genes. I'd say it's a collection of other tendencies and pre-dispositions that are equal parts nature, nurture, and mood.
