It's funny how two forums on completely different subjects yet have similar groups of mindsets. Over in a bass guitar forum on facebook I hear things like "you don't need more than 4 strings" and "Fender Precision is the best bass of all time."
Sounds rightly familiar to the boomers in gun forums who go on about how you don't need a full auto or the 1911 is the best pistol of all time lol.
Most full autos are owned by “boomers”. Where did you get that?
The people you are referring to are “fudds.” Fudd isn’t specific to any one generation.
