That thread just oozes tunnel-visioned fantasy-world stereotypes!
DU folk can't imagine homosexuals being conservative? (BTW, my, possibly incorrect, understanding of current usage is that "gay" refers specifically to male homosexuals)
DU folk can't imagine conservatives having friends who are homosexuals.
DU folk think nearly all homosexuals who advocated for same-sex marriage did so because they wanted to get married (or for their homosexual friends to be able to).
In the case of the latter stereotype, DU-folk will very soon discover - and be ecstatic - that many who advocated for same-sex marriage were really working to fashion a weapon for attacking Christians and Christian churches - the ones who believe and follow the Bible, not the ones who have been their dupes.
