I think you've been reading too much Daily Kos if you think it's an exceptional right-winger who doesn't want to genocide minorities.

(a) Miscellaneous fundamentalist elements of the Christian right who clearly don't support gays have been doing miscellaneous agitation through their missionary arms; African churches have been lobbied (in the passive voice) "to drop ties with mainstream Christian groups." I'm not sure who these shadowy figures are, but it sounds like they're not mainstream.

(b) Everyone is helping support the death penalty for gay people because the Obama administration gave the Museveni regime cash and military aid.

This situation seems problematic. However, notably absent is commentary about people who "say they support gays but are against gay marriage" lending any form of material support through their actions. Is it possible you have conflated several of your political enemies? It's an easy mistake to make, we pretty much all do it from time to time...

I don't think comparing crazy blog commentators is a fair standard for either side. I'm going to come up with something I think is a bit more fair: compare the intellectual component of each side.

* Left intellectuals (ie: writers at the Guardian, Jacobin, etc.): tendency towards hero-villain thinking in domestic policy/class struggle, a tendency to apologize for violent regimes that purported to be engaged in class struggle. Occasional cultural silliness, and fairly commonly prone to apologia for anything a perceived "underdog" does whatsoever. Otherwise, generally quite cogent and able to come up with extensive critiques of the status quo and platforms of action.

* Right intellectuals (ie: the National Interest, The Economist): tendency towards hero-villain thinking in foreign policy, leading to support for violent regimes purporting to "keep the damn dirty Leftists out". Large amounts of cultural silliness, especially prone to believing that hierarchies of authority just are morality, especially prone to tribalism and a bizarre fixation on people's recreational proclivities, especially sexual ones. Often cogent, but not actually consistent in platforms and critiques: usually more focused on rationalizing the existence and actions of some power-hierarchy to which the intellectual is loyal than with establishing any universal moral principle at all (other than hierarchy itself).

It's pretty damn clear which side I'm on, but I also can't think of any facts I've neglected at the moment. Worldwide, the separation between Left and Right seems to really be about principles versus hierarchy.
