The need to protect your offspring doesn’t just transcend species, it transcends kingdoms.
Cool, the need to reproduce also transcends kingdoms, but I wouldn’t be making moral arguments for reproducing at any cost either.
I’m sorry, but trying to reason or shame me into abandoning my parental need to protect my offspring that goes back literally billions of years is not something you’re going to be able to do. There is a long, long history of parents begging their children not to go to war.
There’s also a long, long history of parents shaming or even killing their own children for not going to war for a just cause. This idea of a child being worth committing any evil to save is very modern. You can claim that it’s something that you could never fight, that it’s some biological imperative that takes precedence over everything else, but history, and fuck, recent examples for that matter, very clearly points to that being nothing but an excuse.
