Your analogy is ridiculous.<quoted text>
I disagree. MLK was for liberating those who were oppressed. His focus at the time was obviously for the injustices focused towards blacks in this country but it's easy to see how his views would have extended to the gay populace. Added to that is his wife's testimony and the fact you cannot put words into the mouth of a dead man. There are no indications he would have not supported gay marriage. In fact it's the opposite. To lay claim he would have would be akin to claiming Albert Einstein would have rather used a set of tarot cards to determine wind resistance on space bound rockets rather than utilize scientific means. Martin Luther King was a man about freedom, not a man who supported limitations of the same.
I don't doubt that MLK would have supported equal rights for GLBTs.
Calling a mutually sterile, duplicate gendered half 'marriage' would not fly.
