In principle I agree with the idea. There is a certain happiness that comes when you are living as you love to live. Whether that is Master or slave, Dom/sub, etc. And whether you male or female.
I live in a Master/slave relationship with my wife, and we can't imagine living any other way. There have been times in our happiness that we have thought how great the world would be if every one lived a M/s life like we do.

It certainly is a wonderful thought, but reality is as it is. Let every one live as they are called to live by their own conscience. That is probably as close as we could ever get to utopia.
