Maybe by working with why it feels wrong to do this, if he likes it so much?
Or is it you liking it that feels wrong?
Feelings in such matters are not govern by reason.
If it is you who have a problem, not because you dislike it, but because you do, then I am pretty sure you'll get past that with a little more time.
Also maybe search out a club or the like, and see how many people like it. Perhaps it wouldn't feel so wrong then.
