You do realize, don't you, that included in the dictionary definition of sodomy are acts in which many heterosexual (and yes, heterosexual, married) couples engage in.  Are those sinful and disgusting, as well?  If so, why are you all not decrying the behavior of heterosexual couples?  

And I have yet to hear any gay person describing what they do in the privacy of their bedrooms -- in private or public conversation. So, it seems that it is your imagination that offends you.
