Oklahoma City bombing was done by a conservative, and if you get right down to it, Osama Bin Laden and his cronies are all Koran-thumping fundamentalist conservatives. But libearls do some violent things too. Tree spiking is a relatively common practice that comes to mind, along with violence associated with protests.
But there are definitely more wacko christian fundamentalists than there are commie-kids. And commie kids usually outgrow it when they realize that a life of activism won't get them that pimped out car and huge mansion they always wanted.
