As someone who is also this guy’s age I can tell you 100% this wasn’t hard at all. The Beatles were Boomer music and they were shoved down your throat everywhere and they reeked of your parents’ nostalgia. Nobody I knew liked The Beatles.
If you were into grunge, *everything* was your enemy.
As someone who is this guy's age I can tell you 100% that if you were into Pixies, Nirvana, 120 Minutes stuff, etc. but didn't like the Beatles you had to have worked hard to contort yourself into that special little box. Your enemy, if you absolutely needed one, was hair metal. GTFO here with this.
