And I pointed out, well, once you make it ten, then why would you draw the line at ten? What's wrong with nine? Or eleven? And the problem is once you draw that limit ; it's kind of like marriage when you say it's not a man and a woman any more, then why not have three men and one woman, or four women and one man, or why not somebody has a love for an animal?
