Let me turn that around on you:

If it's really worth $100k, then why on earth shouldn't OP get that $100k if it's going to be taken away from them?

Which is more unethical:

Raising animals compassionately, slaughtering them for meat as painlessly as possible after a healthy, happy life

OR

Letting people who require meat in their diet to live (there are a number of reasons this may be the case) die slow, painful deaths as their bodies fail around them?

It's real easy to say that "no one should ever kill an animal to live" when you ignore the disabilities and chronic conditions that make surviving on plants alone impossible, or prohibitively expensive.

The harvesting of a number of the common foods used to supplement vegetarian and vegan diets—eg, soy, agave, quinoa—are variously destructive to the environment and based on labor practices exploitative enough that they sometimes verge on slavery.

Many, many people disagree with you.

It is not at all a logical, ethical, or emotional contradiction to say that we should have humanely-raised livestock whose purpose is to be slaughtered for meat. We can ensure that they are kept in healthy, safe, and humane ways during their lifetimes, and are killed as quickly, cleanly, and painlessly as we can reasonably manage.

And, um, the meaning of "humane" is only loosely related to "treat like a human." It means "treat well, view with compassion", and similar. We talk of things being "humane" or "inhumane" in how we treat each other, too. [0]

Humans have been raising meat animals with compassion and treating them well during their lifetimes for longer than we have had written language. Veganism/vegetarianism is not even physically an option for many people, excludes many cultures' traditional practices, and very, very often requires (or at least tends toward) supplementing with foods that are at least as unethical as factory farming practices.

The US most certainly does not, nor ever will need to do anything so horrifying and cruel.

That's like saying "ugh, now I need to beat my son every day, or he won't do what I tell him". Sure, if the only tool you think you have in your arsenal is violence, that seems like something you "need" to do, but in the real world, we have many other tools that are much much more effective at achieving our goals. They just...might require actually caring about other people, and treating them with respect and human dignity, and *gasp* possibly even acting like something other than the most absurd caricature of a "manly man" to ever man.

Now, what's abundantly clear is that nothing like that will ever happen as long as any party that remotely resembles the current Republicans is in power in the US. So hopefully that can be another good reason to get them out permanently.
