Actively trying to like something is already a sign that you don't like it intrinsically. Continuing to try strikes me as...some expression of over-socialization. It's okay to pursue things you actually like for your own sake.
If I hadn’t pursued things that initially didn’t click for me, I’d be missing out on what are now my favorite… everything, really, and still stuck with some things that are by-comparison so bad that I can’t believe I ever liked them, at least not to the degree that I did.
I don't dismiss new things off-hand. I explore them until I'm sure that initial distaste is real. And I definitely don't bash my head against them over and over, to the point of wasting time. We are not obligated to like anything on anyone else's account.
