1. He and his partner obviously discussed this very carefully
2. And?
3. Remember, it only became commonplace towards the end of the 80’s. Maybe they didn’t have the money for such a procedure? Maybe they were afraid of being refused? Maybe the procedure only legally allowed the use of sperm banks and not new donations from involved individuals? There’s any number of hypotheses, and their solution was a bit unusual, yes, but that doesn’t make the individuals involved or the whole idea moronic.
4. His sister asked him. With such an argument, if you’re very close siblings, it’s difficult to say yes, but also hard to say no. But you’re also forgetting that sexuality exists on a spectrum. Just because he identified as gay doesn’t mean he would have been absolutely horrified/disgusted/incapable of having sex with a woman.
how can you give up? You’ve posted less than a handful of very short responses [3 (not including this last one) to be exact,] the first and second of which indicated that you didn’t understand the entire situation and merited the responses they received. If you did understand the logistics, why would you even ask “Then how did he get an STD by donating sperm?”
