I'm a rock elitist, because at least people can dance to rock.

I can appreciate jazz, but to me, it's a more intellectual form of music. In that sense, it's akin to technical death metal. Both make me feel musically inadequate.
If you think you can't dance to jazz, you need your groove sensors checked.
Example 1: Snarky Puppy. Bassist Michael League composes and arranges all their stuff. He also shames anyone who thinks that a P-bass doesn't belong in jazz music.
Example 2: Jukka Eskola. I mean, seriously, just try not to tap your foot to this poopie.
Example 3: Herbie Hancock. Needs no elaboration.
Example 4: Robert Glasper Experiment. Fluid, sexy blends of jazz and r&b, combines virtuosic musicianship with head boppin grooves.
Also I think that there are indeed many elitists in every genre, but all those people should be ignored because they're playing with their heads stuck inside a box of whatever tropes in music they've grown used to. It takes some work, but if you actively seek it out there is fantastic musicianship and songwriting to be found in every genre (yes, even country) and listening to that attentively will put you, as a musician, leagues ahead of the jazz fanatic who has transcribed all of Jaco's solos or the classical dude who plays Bartok all day or the metalhead who shreds nothing but (insert iconic metal bassist here)'s riffs.
To address the question of why teachers shove jazz down your throat, I think that's because historically speaking it's one of only a few genres of music that have been deeply analyzed in an academic/music theoretical fashion, and so naturally it has spawned the most methods of teaching music and applying music theory. Not to say that other genres couldn't be approached in the same way and that you couldn't learn just as much from them, but teachers who decide to go with that approach might, in some senses, have to reinvent the wheel. However, I will defend the decision to teach jazz because I feel that it can fluidly incorporate aspects of other styles (again, Snarky Puppy and Robert Glasper are really really great examples of this), but I digress.
Main point, elitists of all kinds suck. Don't listen to them, and furthermore, don't let their vitriol destroy your taste for their chosen genre of music, lest you find yourself developing the same kind of musical tunnel vision that turned them into elitists in the first place.
