It could be considered tradition to use proper grammar and punctuation. I don't see you following it. Why? Because it's old-fashioned and a waste of time.
you don't even pay attention to what you write and should before you attempt to branch out. 'No matter black white or beige, chola or orient.'. you can't mean Oriental and where is the comma between 'black white'?
I see no good reason to not allow it. Seems pretty heartless to me. It's like saying different races can't marry each other. That's the glove you are putting on when you say that two women or men in love can't marry each other.
It's there choice whether they want to or not, nobody else should tell them how to live. If it's not about them they could stay the hell out of it. Shouldn't concern them anyways cause it's not about them.
If there is same sex marriage. Why not a brother marrying his brother or sister? How about 3 people getting married? How about someone marrying there dog? Or mother, father, uncle?how about the skies the limit?
Yeah... Like candy floss and puppies.
