That's not close to the only difference, and often enough they're not reversible. I'm not even sure there's enough data to prove it's safe and reversible on infants anyway, prove otherwise if you can.
Also you'd be punishing gay people for no reason, they're completely unrelated to the issue yet you'd be violating them too and you ignore this.
Biggest thing to remember, and for you to ignore, is that 99% of abortions result from consensual sex, meaning they're responsible for their own pregnancy. "Punishing" them (holding them accountable and responsible, how tragic) is warranted, unlike your proposed blanket abuse of all innocent babies including homosexual ones who are not related to the matter of the process of procreation at all.
Let me sum it up for you:
Whores get knocked up, they're held responsible for their actions and unallowed to kill their problems away
VS
Sterilize all men as innocent babies who aren't responsible for a single thing, including fagbies who wouldn't procreate anyway
If you don't see the differences and can ignore them again then you're more retarded than I can possibly imagine.
