My statement was on mass SHOOTINGS (did we want to get INTO bombings as well?? Left wingers have THAT market cornered in spades!  Ask obama's buddy Bill Ayers for starters!) ...and there's not enough space to BEGIN to list the shootings done by liberals....
And if you consider shootings by the Klan or white supremacists as conservative, sorry to disappoint, ...those are progressive/liberal/democrats....not conservatives.  The Klan has always been part and parcel to the DNP. And Progressives base their "Utopian Society" as being all white.  There are "fringe" on both sides, however, those who vote and proclaim democrat/liberal status are far and away the shooters in the mass killing arenas....Which are known in left circles as "gun free zones."
