When you paint targets on people, other individuals may cause them harm, seeking some measure of your acceptance. Some here might have actual "followers," not fans or confederates-in-cause. Some individuals here, and you even as a group don't have to "ask" for somebody to be hurt, just imply that it is consistent with your wishes. When somebody expresses targeted violent sentiments, and you don't correct them, they perceive that as a ratification. (While "mattd" is a self-identifier, others might not be. You might not even know about them.) Such "suggestions" are a time-tested method of obtaining plausible deniability for violent political action.
I would think SOMEBODY can at least make the effort to say something when violent sentiments are expressed. Guess not. ~Aimee
