Same as when they presume that because David and Jonathan loved each other more than they loved women, that means they were lovers. For heaven's sake, how cliche is it that men never let their girlfriends or their wives interfere with their brotherly friendships with their buddies?
In fact, I find it difficult to believe a sizable percentage of the members of the MCC really believe that the Bible supports the idea that David and Jonathan were homosexuals -- it's just that they feel they MUST believe it in order to feel they are acceptable to God without correcting their behavior.
Here's a good reference for scholarly refutation of the MCC and other "Christian" groups' homosexualization of Bible doctrine: Responding to Pro-Gay Theology, written by Joe Dallas, formerly of the MCC. Dallas is loaded for best shots the Gay-stapo can take, which is why you likely have not heard of him; the media stay away from him.
Really..the idea that David who had 100s of female concubines, and even committed murder to get another man's wife....was actually gay is absurd.
But don't underestimate "gay Christian" capacity for self deciet.
It's amazing to see the contorted logic they will resort to in order to reinterpret perfectly clear scriptures in some alternate, gay friendly manner.
This touches on one of the saddest damages that the SAD agenda has wreaked on our culture. Back in the 50's men could have friends, close friends, friends even closer than a brother, without anyone batting an eye. Today if two men are that close they are almost always assumed to be 'gay lovers'. This has caused many men to isolate themselves from others.
Unfortunately early isolation is one of the leading indicators of SAD. So by accusing the innocent of their own perversion the SADs have scattered a seed of perversion throughout our culture.
Men, especially Christian men, have to stand up and build accountable relationships with men again. Christian wives have got to allow their husbands to go out fishing with the guys (or whatever the guys want to do) they have to encourage their husbands to have friends. (within reason of course)
