I think the biggest sin of all is their sense of entitlement. I know the running joke is how entitled millennials are, but nigga where'd they get it from? I know plenty of Boomers who love to complain how pitiful young people are, but the biggest sin of boomers overall I've come to realize- is they don't let their kids grow up. These faggots have an absolute visceral reaction when you tell them to pass down the torch.
I see it all the time. My favorite game is to goad them into it. "Yeah the younger kids are pathetic".
"Yeah my kid can't even change a tire. It's ridiculous."
"Yeah....so did you ever teach them how to change a tire?"
"What? What's there to teach?! It's a tire! It's not fucking hard to change a tire! When I was 12 I was doing my own brakes"
If you really want to start a fight...
"Did your kid do brakes at 12? No? Well then who's fault is that?"
Bottom line, you get the full mask drop. Boomers universally don't seem to get the concept that the time to pass the torch isn't when you're too old to do the job, it's not when they're 50. It's not when they're 30. Or 21. Or 18. The time to pass the fucking torch is as soon as you can possibly do it. If he's old enough to hold a fucking flashlight, then he's old enough to have some jobs passed onto him. Instead, what I constantly see from Boomers is them demanding their kids know how to do things they never showed them how to do. Most of them won't even fucking ask. They'll complain about how the floor isn't vacuumed, but if you ask them "Did you ask them to vacuum it?", they'll always go "No, he should KNOW when to vacuum it". Well, bitch there's your problem. Parents always complain about TV and video games, but they forget they're the ones who hold the keys to those things. If I unplug the fucking WIFI, guess what? No Fortnite. Now you have to mow the lawn. Of course kids fucking hate it, but that's how the world works. What you don't do, is hoard even the most basic of responsibilities and burden yourselves until you're have one foot in the grave and get pissed off when nobody knows how to do your daily routine.
The worst aspect is how this extended into the professional business world too. It's always old fags into their 70s and 80s who refuse to retire. They refuse to hand off those managerial positions to younger existing employees, they always hire outside other boomer faggots. Then they're surprised millennials hop from job to job to get raises. Nigger, why fucking stay? You don't give them advancement or raises, there's no reason for them to stay.
