Well in that case, the image is based on the false dichotomy that doesn't exist of the parties' policies. Most dems don't want to remove all guns. They just want to keep guns out of crazies' hands and some want to limit availability of particular things so any subsequent mass shooter has a harder time just endlessly popping off shots like the Vegas shooter... They do not fail to understand guns.

Ontop of that, vaccines are a very strange thing to put in opposition to guns. I know what you're trying for, but it is again based in ignorance. Vaccines are a universal good. There is a reason, a good reason, vaccines are required in order to go to schools. Whether the pharma industry works off of capitalistic practices is a wholly separate thing. Just because big pharma is a piece of shit capitalist enterprise should not reflect poorly on vaccines themselves.
