Conservative commentators really should drop this silly game of hate rhetoric equivalency (i.e. Both sides do it!) because every time they try to play they just look dopey.

The latest in the queue is Jennifer Rubin, who writes Right Turn for the Washington Post. Her rather lame angle of attack is that liberal activists who gathered in Rancho Mirage, Calif. over the weekend to protest the annual political confab sponsored by Tea Party founders and right-wing billionaires Charles and David Koch are just like conservatives who have been criticized for embracing dangerous, insurrectionist hate speech.

How does Rubin know? Because she posted a photo, supposedly taken at the anti-Koch rally, that shows a single man carrying a cardboard sign that reads “Neuter Feral Fatcats,” and includes a painted swastika. Rubin reports that more than 1,000 protesters gathered over the weekend, and her proof that the “mob” peddled hateful, dangerous rhetoric? A single guy with a foolishly inappropriate Nazi sign.

In Rubin's telling, that's just like right-wing activists, and their multi-million dollar right-wing media outlets, who have embraced an avalanche of Nazi rhetoric for the last two years. So why aren't Jewish Funds for Justice condemning the liberal, weekend protest, Rubin asks.

No joke. That's actually her argument, that a civil rights group ought to condemn a single guy with a cardboard sign the way it recently condemned Fox News. Why? Because that misguided activist in California carrying a Nazi sign is just like the most-watched cable news channel in American wallowing in Nazi rhetoric for more than a 100 weeks running. For Rubin, those two examples are equivalent.

Note to Rubin: Quit while you're behind.
