I agree with you on this. But we are not talking about whether you ask someone to prepare turkey for you for Thanksgiving. We are talking about whether you are willing to undergo an operation to remove your ability to digest animal related products. The decision to have a vasectomy is not something to be taken lightly.
It is a possibility. However, something could go wrong that would result in the destruction of the sperm. I find it amusing that they way you throw around the idea of people having vasectomies, a power outage in a city’s sperm bank could result in half the city’s males never being able to breed (since a good portion of men do not wish to have a child at some point in their lives and you would have them all get vasectomies).
True, I would not advocate asking the woman to compromise her morals either, but if the man received the woman’s assurance that she would not keep any fetus she became impregnated with, and she changed her mind later, I would at least let him wash his hands of the situation if it would help him with his moral dilemma. If a vegetarian somehow partook in an act that made him/her partially responsible for the slaughter or countless animals without any good reason, I would allow that person to leave the scene as well rather than have to recoil in constant horror at the carnage he/she helped create.
