There's a huge emotional problem too. The fact that a mother will always be in a positron of power over her child. And with that power comes the responsibility to do the right thing and not psychologically **** up your child by using them for sex or abandoning them. Or abandoning them, then showing back up in their lives 30 years later, stirring up all their emotions, THEN using them for sex fire 10 years, further complicating their emotional sense of well being and fears of abandonment.

There are so many things wrong with this situation it shouldn't even have to be debated. It's not just a genetic problem. It's so much more than that.

Ignoring the huge emotional implications of being abandoned by your biological mother then later having her come back and use you for sex is ludicrous.
