I love that conservatives are still angry about the Crowley situation, which was totally legit. Obama did say it was an act of terror immediately. And then, like a good moderator, she made it clear that there were some things up for debate and some things that weren't. The truth is the truth. If Obama were to say, "No you don't understand, the world is flat." Well, it's the moderator's job to focus the debate on what matters, so it's perfectly acceptable to say, "wait, no, that's not true...these are the facts, now let's talk about the issues up for debate in our non-flat world."
If Mitt was more interested in the substance of the issue rather than the bs semantic argument "oh gosh, the president didn't call it a terrorist attack." Who the heck cares? What does that have to do with anything? It harkens back to this weird conservative belief that Obama doesn't love this country enough or he's just not truly American enough. "You see - he didn't call this terror; he doesn't get it like the rest of us do." As if the word is more important than the facts that happened on the ground. So the tactic backfired. Rightly so.
