OK, what the hell. I'll go.
1. People who don't see the value in old things: Old calibers, old cars, old friends.
2. People who say "OK, Boomer", without understanding they've just received some hard-earned wisdom.
3. People who say "OK, Boomer", without realizing I'm actually Generation X.
4. Gaslighting. Not lights running on gas, but rather people who say things like "listen to the crowd saying 'Let's Go Brandon!', when we can all clearly hear three other words. Stop insulting my intelligence.
5. Inflation.
6. The Designated Hitter Rule. There should be a Constitutional amendment banning the Designated Hitter Rule.
7. Catamarans in the America's Cup.
8. Fluorescent "squiggle" light bulbs that have to warm up after you turn them on.
9. People who say the M1911 pistol is "unsafe" as a carry gun because you have to remember to take the safety off.
10. Hipsters. Especially the ones guilty of points 1, 2, 3, and 9.
11. Using a shoot-out to resolve ties in hockey games. Hey, sometimes there's a tie. It's an imperfect world. Screws fall from air-ducts all the time.
12. The "Everyone Gets a Trophy" mentality.
13. Socialism/Communism/Marxism/Authoritarianism.
14. People who don't like things who want to take away other's ability to have those things. I'm looking at you, gun control advocates and those forcing me to buy an electric car!
15. People who think electric cars will solve every environmental problem, without understanding how much colbolt, lithium, copper, etc. you will need to mine, and the inability of our current grid to support it.
16. Mondays.
17. Our descent into an Idiocracy.
18. Automatic spell checker that "corrects" what I typed to something that's not what I meant.
19. Long range hunters. You'll impress me more by telling me how close you were able to stalk it than by telling me you fired a shot at 1,000m.
20. Cars that need a special "dealer only" computer to do simple things like reset the oil change reminder.
There's more... but that's a start.
Now, for feats of strength, who wants to join me to see who can trim the cat's toenails?
