If anything, The Beatles prove how *little* the ability to play well live has to do with a band's greatness. But I'm not going to waste my time extolling the virtues of The Beatles- you know what they are, even if you don't agree or won't admit it. All I'll say is the "bros The Beatles actually weren't great musicians" argument is old and tired and lost whatever edginess it once possessed decades ago (especially since even the biggest Beatles fans will happily admit this so there's no debate to be had, really).
Also, yes Trung has OCD, is (probably?) on the spectrum and posts lengthy posts with bizarre options stated as facts. We all know this. If you want to disagree with every single bizarre opinion and constantly call him a moron, feel free. But it seems like a waste of time to me. And kind of mean (yeah, I know, this is Music Babble and calling people out for being mean makes me a f*aggot). Maybe try doing what I do- roll your eyes, pick your battles and scroll on.
