Why is it ok to abuse people from Mexico but not animals?

Is this a joke? Where did I say it's ok to abuse Mexicans?! You lost me here.

What is your opinion of 'lesser' animals that are omnivorous yet still eat meat? Are they monsters?

Are you in survival mode like wild animals are? Or do you enjoy a comfortable life thanks to scientific development? I have no issues with humans in developing countries or tribes that still live in harmony with their environment to eating meat for survival.

What is your opinion of the species of ant that farm aphids for milk and meat?

Again survival here. But are we really going to define our actions by those of an insect? Surely all of this grey matter should allows us to make decisions based on critical thinking.

What would you say to only eating animals that have died of 'natural causes?'

Gross! If that makes you happy, I have way less concerns for an animal that is already dead than those that are bred for dying.

What would you say to the genetic engineering of organisms that produce meat but never have enough nervous tissue to even be considered alive?

I think this is an incredible thing to even consider. This is a huge hypothetical and a sidetrack from the animal rights debate. I think this touches other realms of ethical debate. Is it ok to use genetic modification to create an unnecessary commodity that can be easily replaced by plant alternatives? Anyway, if you want to eat lab meat, that's your choice. As long as it doesn't hurt anyone, I'm ok with that. For now let's focus on the animals that are currently being tortured and killed, we can discuss GM meat when the time comes.

What would you say to the undeniable fact that there are more white-tailed deer alive today than any other point in history, because of human management, supported by profits from hunting?

That hunting is used to save species is the biggest oxymoron. That's not true conservationism, it's an excuse to keep on hunting. Do some research on the species that have been hunted to extinction.
