Actually, Justin, Horowitz was the same when he was a Stalinist Black Panther groupie. He simply crossed the aisle (though in the case of the late Panthers, it wasn't too far a walk). He's always been a hack and liar and cheat. In the late-80s on Lewis Lapham's short-lived PBS show, Hitchens (when he was still a socialist) utterly took Horowitz apart piece by bloody piece over the issue of "Second Thoughts" about the 60s. Funny thing was, Horowitz was too stupid to recognize that the blood was his. He wouldn't stay down. "Why can't Christopher Hitchens PRAISE Ronald Reagan!" he squealed, handing Hitch yet another juicy piece to rip into. Talk about lovely to watch.
I debated a former Dartmouth Review editor at Queen's College over the issue of PC. He was off ranting about the pro-Sandinista media, how the education system was run by Marxists, etc. I began my rebuttal by reading a couple blind quotes that called for the young to be shaped and molded along certain lines. That their minds needed to obey specific rules and systems of thought. I asked the Review guy if he felt this was PC at work. He replied it was. I then revealed that the two quotes came from William F. Buckley and Benjamin Hart, one of the founders of the Dartmouth Review. He didn't have an answer for that.
All the above is a long-winded way of saying that the right is easy to debate. Most of them are idiots. The better ones give ground to protect the real arguments they want to make, but these are few and far between. Most are like Horowitz, charging directly into the blade.
