Folks who say tattoos are for stupid people are generally middle-management aspirational, ass kissing sycophants who'd throw their coworkers under the bus to get ahead in their middle class, deadend occupation.
They assume everyone who is heavily tattooed is either a tattooist or mired in unemployment. I must admit I do love getting followed around stores by security personnel who earn considerably less while the "tattoos are for stupid people crowd" presume their mental and professional superiority. The type of person who says things like "what will they look like when you're older?" As if they've planned out their life for that pinnacle of being aged and incapable yet will ironically end up eating a shotgun in their late 50s with spiralling credit debt on account of trying to keep up with the Jones's.
