Sorry I think you're mostly mistaken. Killing the by products (males) is absolutely necessary to producing these products on a commercial scale.

The right to choose probably should end where another's life comes into question.

If we don't need to kill, why would we? It is like smacking a child for no reason. Why hurt the child? Why hurt and kill animals?

Personally, I cannot find strong enough reasons to do so. Nutrition isn't one of them, nor is a temporary taste on the palate.

Thanks for the respectful discussion. Take care and I hope to see you back here, too.

Cheers.
Nick.
