I do feel for the couples who went to the legitimate donor clinics and ended up with this psycho who obviously wants to leave his genetic legacy to the world. I also feel sorry for the thousand children who are his progeny, particularly the ones whose mothers just randomly decided that it would be a good idea to go and procreate with a total stranger, because he had nice blond curls. The IQs of these poor kids will probably prove to be quite the number...And maybe they did it because it was free?
I have absolutely no sympathy for the people who reached out to this random stranger and accepted his word that he had only fathered three or four children, oh no, maybe 25 children because now he was helping with second and third offspring for the couples that were already successful and had one child, so the lies just changed. No vetting on their part of his medical history (only what he told them), actually agreeing to having sex with him, so it would "work better" (I think one woman agreed to that I'm just so disgusted I have no words), waiting at the mall for the "sample"; commenting on how gross that is, because he is obtaining the sample in a public bathroom at the mall, but taking the sample home anyway...I'm sorry, you are trying to conceive with a complete stranger, and you want a child so badly that you don't care to look into his background.
Now your child has 50% of this narcissist's DNA. Good luck to you and to your poor children.
