I agree with most of Dolor's comments. However just because times change, doesn't mean they have changed for the better, or that current practices are the best for the parties involved. It seems what you saying is there are a great many single parents these days, and that makes it okay. Well, I don't think that is logical. I don't oppose single parenthood, but I do think it is a lesser option. Also, I think the person that it probably matters most to, the child, is not part of the discussion.
However, I don't think society has the right to make it illegal.
Thank for the opportunity to express my thoughts.
