If this reasoning is correct, then conservatives should be becoming worse at gauging liberals' position on social justice-related topics, considering how their reporting tends to be dominated by extremists as well.
What exactly seems fair? The reply you're responding to asserts there was a "violent fringe that was making the most noise and claiming the most airtime." Is that fair? The discussion, at the time, concerning gay marriage in conservative national media was dominated by a "violent fringe"? Were their calls for violence? Were there even suggestions that violence "may be necessary"?
I'm going to reach here a bit, but are we going to rope in the Westboro Baptist Church and pretend these people were the "conservative" response? Even if we do that, do you recall them—as odious as they are—being violent or advocating violence? And if we're not pointing to them, who are we pointing to?
