|Long time ago ...
I entered a tech. U where the Student Union had a strong radio amateur ('ham') group. Holding a ham license, I applied for membership. Like so many student groups, they have strict rules for accepting new members, far beyond just signing up. So I was called to an interview, to verify that I would fit into the group.
At that time, I listened a lot to classical music, and it happened that I had already bought a concert ticket conflicting with the time for the interview. So I returned a reply, asking if the interview could be moved to a different time.
I didn't hear anything more from the ham group for several weeks. In the meantime, I had heard from a friend of mine already a member of the ham group that there had been a discussion whether someone who listens to classical music would fit into the group. When they after several weeks came up with a new time for an interview, I decided: If it was considered seriously to refuse to accept my membership in the ham group because of my musical taste, then I guess that the social environment in that group would not be one where I would enjoy myself, regardless of which musical taste we are talking about. So I reported back that I was no longer interested.
I guess that (e.g. based on chromosomes) being dated by you would be outside my interests anyway. Even if it was, after your remark I would turn it down anyway, for similar reasons. My classical music period was over decades ago, but now that you state that I would have been rejected anyway if I had kept my sense of classical music,
You make me suspect that for you, friendships are similar: You couldn't be a close friend to someone doing classical or folk (regardless of XY). Then I say: OK, so let's not be close friends, then. A friendship requiring identical musical tastes sounds rather fragile to me.
You might be joking. But even if you are joking, I can very well imagine people of that attitude (ref. that ham group). If you tell me that you are joking, I might want to introduce some of my favorite folk music to you ...
