"You know this thing you like? Have you tried not liking it? Yeah, it's because I don't like it, and I just really think everyone should give disliking it a fair shot, even if they've tried it and think they like it, that just might be because they haven't really made an effort to dislike it"
ETA: Or, to make it simpler, most people are more interested in finding things they might like than in finding ways to no longer enjoy things they already like.
I guess so, but the two come as a package, don't they? "Don't watch that, watch this," where the reason for being pro-this is also the reason for being anti-that.
