Sperminator needs to be on the hook for child support.
Why?
There was no physical act of intimacy involved.
He didn’t buy the cow. He didn’t get the milk for free.
Should a kidney donor be on the hook for the recipient’s medical bills?
All he did was contribute some cells. Remotely.
I would assume that there was some sort of contract signed that would let him off the hook. He would be an idiot not to.
