I liked the USCCA initially, but then I started getting spammed with their braindead advertisements on YouTube which are apparently aimed at the most ignorant and irresponsible gun owners in the country who don't even bother to learn about state and federal laws concerning firearms/self-defense.
Then at one point, just because I was curious to see how dumb their little guides were, I attempted to download one from their site, only to hit a paywall which required me to become a paid subscriber to their organization before they'd allow me to download their "free" guide.
Nope, I like Gun Owners of America and their no-BS approach.
