I have strong contrasting thoughts about neutering animals and there's nothing I can so about it?

Why do people feel like neutering animals is so crucial? Why is it so normalized, at the point of celebrating it like a birthday party in the case of domestic animals, but with humans it's seen as a macabre and grotesque thing? I know that there are double standards, but I refuse to see animals as objects of use and consumption to alterate as I please. What if somebody took humans and neutered them? If that were you? Vasectomies and tubal ligations aren't the same thing, because you get to keep your sex hormones and it's just the Vas conducts and the tubes. I'd rather have no pets than being forced to remove part of their sexual organs if there's no need to. It's not just dogs and cats, but also animals like horses. Geldings are almost fetishized.

Humans are so obsessed over sex, and, apparently, they even feel like the only ones who are free to have sexual desires. That's the reason I don't even feel like getting with a man.

I could see why would somebody neuter animals, but, again, what about humans? If I were so pro - neuter like many Americans, I'd be either for humans and non - humans or neither.

Don't try to feed me neutering propaganda, I'll think the same. Show both sides.
