The abundance of evidence that the Holocaust shooter harbored strong animosities against the two most recent Republican presidents and  had little in common ideologically with the mainstream of modern American conservatism notwithstanding, certain left-of-center pundits and bloggers have attributed his murderous actions to (what they define as) “hateful” conservative rhetoric.

And yet, as they make the jump from the shooter’s actions to their ideological adversaries, they do little to illuminate his motivations, exposing only their own prejudices against conseratives. 
Thus, since conservatives don’t fit their narrative of what we’re supposed to be, they have to resort to name-calling because arguing with us would mean acknowledging our ideas.
And by dint of acknowledging our ideas, they undercut their (at that point, previously) prejudiced worldview.

They might find it easier to talk to us, if they tried to see us as we are and not as their prejudices define us.
