To "fan" a division means you have to recognize an underlying faultline is already present. So, you should have added the qualifier, "further" divide the GOP. (I mean it's not like the GOP is united in presidential candidates already, right?).
It's the pro-Romney folks who want to pretend that there is no division, and to just right it off to "bigots" and "loonies."
And this way, they are acting like the "left," whose philosophy is "all we have to do is label somebody in such a way and we can effectively marginalize them."
Shame on so-called "conservatives" to use the left's tactics!
Point taken.
