I am not being funny.
Your argument seems to be that if you don't know what you are dealing with, it is OK if you are taken advantage of.
My argument is that, while the person might not be an expert, it is NOT OK to take advantage of someone because they don't know any better. When someone tries to scare new people, it falls under this category.
The gun world can be complicated AF. It took me a while to learn all the flavors of SIG 365, and I still can't memorize all the damn Glock models with their bullsh*t naming. Most of NES can't even agree on what is a damn pre-ban Glock mag and there is mixed messaging from pant sh*tters on pre and post Maura junk. Add to that the mixed messaging from gun classes from "experts" and bad FFL advise to noobs. Yet, you say it is OK for someone to be taken advantage of becuase they should know better.
The car argument is the same logic.
