The issue was not whether you should get your animal spayed or not.. If you are a responsible pet owner, you can research from online articles, as well as taking advice from veterinary professionals, then making a rational decision.
You made a comment suggesting that butchering a dogs ears for mainly cosmetic reasons was the medical equivalent of spaying. The OP agreed with your comment and indicated that he wanted to have this procedure performed without stating what he felt the benefits were, rather he wanted to segue into a discussion about veganism, at which point I had heard enough.
Irrespective whether you agree with spaying or not, I still believe it is incorrect to state that, cropping a dogs ears is comparable to having a dog neutered, that is why cropping has been banned in so many countries.
