Actually, the abnormaility of homosexuality can be proven through logical analysis. But I guess because logic pre-dates Christianity, it too is not legitimate...
It would seem to be that your "tolerance" of homosexuality is based on fear of being labelled a "bigot" and "homophobe"--a term that you yourself apparently like to bandy about.
Actually, yes it is. The child has become a pawn in their attempt to establish homosexuality as "normal".
It's possible to discuss the concept without actually visualizing the act. If you talk about incest, do you actually visualize yourself engaging in incestuous relations?
