Thought I'd post this for anyone who's interested:
According to a feature article on Reuters, the NRA's got a list of companies, celebrities, and others whom it considers to be anti-gun. Now, thanks to a grassroots movement, it appears that ordinary citizens can sign up to be on the list, should they so desire.
I've always found it amusing when an organization or individual with somewhat shady policies gets a little bit of karmic comeuppance by having those policies turned on them.
