It’s definitely legit: http://thomas.loc.gov/cgi-bin/query/z?c111:H.R.45:
It only takes 1 person to get the ball rolling. With a STRONG anti-gun Lib controlled Congress and another in the White House, getting this passed is not as far fetched as it would have sounded even 1 year ago.
As I recall my history, they said something very similar about the gun ban in Nazi Germany (Oh Honey, that Adolf is such a nice man who has our best interests at heart). If we fail to "get all worked up" and voice our descent, this has a better chance of getting passed.
