This may be a dumb question, but what sort of proof is there of these companies being "anti-gun"? I only ask because it seems all too common these days for many business, small and large alike, to get unfairly vilified on the internet based solely on the old "I was told by a friend who's brother said he heard from somebody else, etc etc" type stories, and the next thing you know the pitch forks are out and nobody really knows what's what...
Now this list could be 100% accurate, but to post a thread with nothing backing it up seems a bit pitchforky...
