To my mind, the whole idea of marriage is to be with a partner, to procreate and maintain the species. Procreation is part of the natural order in nature, so I see no point in two people of the same gender becoming attached in marriage. If they want to be together then they have a choice, and accepted as they generally are, there is no need for them to hide their relationship. The 'wanting to get married legally' thing is not a necessity and if a same gender couple want to have some legal rights then can they not draw up legal documents to cover their relationship without involving 'marriage vows'?.......
I believe this whole thing is not about someones rights as such but a snowballing crusade which started somewhere/sometime by some same gender couple who came out and wanted more.
Always ready to be corrected of course....Mike
