Well, we already do.

According to a lab technician at a hospital, 1/4 of children born are not the fathers, just based on blood types.

I wonder what the numbers would be if every father got a DNA test done?

But, we live in a world that says, to the first man it finds, you will pay for the baby.

I wish we would have an adult conversation about this. Because being stuck with funding another man's child is not cricket.

However, this is all going to change soon.
Get ready women.
The baby will no longer be considered the mother's.
It will be considered the community's. (or tribe's)

Congratulations feminism.
