That's from a political cartoonist for the Virginia News Leader.
If the clock were turned back we'd see this sort of thing with a racial misrepresentation instead of a "class" caricature. Is this any better? Is it any more accurate? Of course not, but it seems to be common anti tactic to demonize gun owners and RKBA advocates.
Simply put, the majority of gun owners are middle class. The vast majority of RKBA advocates are educated (look at THR for example), politically active citizens.
If you want to respond to this stupidity, please do not play to the stereotype.
