Umm! Posters like that can be annoying, however in the case of the poster DJS and cantleave are referring to, this topic is so disturbing to them that I suggest something very deep is an issue in their deepest psyche. Therefore I recommend being kind to them, as we don't really know who they are, or what is going on in their lives, or the extent to which their lives have been damaged by Christian ideology,
The issue of same sex attraction clearly causes some people great anguish. Why else would we see the terrible crimes that some homophobes have committed, or the violent, excessive language that is sometimes posted. I'm not sure precisely why that is the case, but think it likely, that since a satisfying sex life has much greater importance in our lives than Christian ideology allows, that the internal psychological rifts brought about by Christian attitudes to same sex attraction causes an emotional state approaching hysteria.
I recall an idea perhaps originating with Michel Foucault. That the causes of hysteria (i.e. exaggerated or uncontrollable emotion or excitement ) are to be found in the disorders of a person's pscyo-sexual life.
I cant claim an expert knowledge of Foucault's ideas, but can see where the idea (which I just attempted to express) may take us.
