It was the gun was used to kill their demi-god and ruin their fantasy. You remember the fantasy, the one with the president who supposedly lived in Camelot like a king even though this was still most definitely a Constitutional Republic. Once they ban that one gun, all the gun control shit will cease and they will be happy to only push things like: Obama-care, gay marriages, eating less meat and transgender toilets in grammar schools. Too bad Richard M. Nixon did not beat his ass in the election in 1960 because had he done so, none of this gun control shit would have ever taken off. It's also too bad that if they actually are successful at banning that one rifle, by the time they have gotten to it, they will have banned every other firearm ever manufactured. Fuck the left.
All the best,
