I suppose so. What happens when a man leaves his wife and kids for another woman?
I think the question is whether there is any difference whether a man goes to another man or a woman to another woman to the children. Yes, I believe there is. It's bad because it show adultery to the children, but man to man may be worse because their is no woman to civilize the man. There is a higher chance of Sodomy.
Woman to Woman has worse problems too, but they are more subtle. The mother factor may be confused as well as marriage between a man and a woman not being promoted.
In both cases, the children of such are much less likely to marry in the future. This is proven in Scandinavia where more than 60% of children are not in married families. In these countries child abuse has increased dramatically.
In any case, the thing to remember here is this is about children. The Lord said that if you mislead, one of these little ones, it would be better to have a millstone around your neck and be thrown into the sea. Marriage is one of God's first institutions. It's like social security, mess with it and society and kids start dying.
