I’ll second that. No disrespect is meant to FR or any other site, but assuming things posted on the internet under a screen name will always remain confidential is not a good bet.
If Obama wins, the ‘security’ around him will be intense and invasive. Those posting things online out of frustration could run the risk of being accused of making threats. Think of what Clinton/Reno turned the FBI into. Post Patriot Act, with Obama and a possibly fillibuster-proof Dem Congress, I am a little nervous about how government power will be unleashed against ‘crazy gun-nut dangerous right wingers.’
