(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...
