I don't begrudge anyone their love of Taylor Swift either. I just think that it's mostly because that's what was fed to them rather than because of any genius she may have.
I, also an older man, don't spend much time disliking pop culture, whether it be Talylor Swift or 6-7, neither of which matter much to me despite having a 9 year old that said it pretty constantly last year. I save most of my hate for the fascists ruining our world.
