>So if you gave someone Covid and their lungs failed, they have a right to one of your lungs
Yes, if you can
1- Prove that I infected them
And,
2- Prove that no other solution would save the infected person, and organ donation would
>Should men be required to donate organs to women they got pregnant
Not if the impregnation was consensual. The person infected with Covid or hit by a car didn't consent to those actions, but a pregnant woman consented to impregnation unless she's raped, therefore she should accept responsibility for the associated risks. Rape is one of the very few reasons where abortion should be allowed. But it's something like 0.1% or so of abortion reasons, the vast majority of abortions are morally indefensible.
Should men be required to donate organs to women they got pregnant, if indicated?
This is obviously very silly and not thought out. Banning abortion is just as silly.
