Morals are subjective, I don't consider myself the arbiter of truth and I also reject theistic positive claims stating otherwise such as objective morals or free will. Personally I know I can survive without eating animals, so I'd rather not be indirectly involved in the killing of other animals where it is reasonably possible and I don't consider humans more important/superior to any other animals, generally.

I think you could get a lot of people to even admit to valuing very old trees over a lot of people too so even some plants are worth leaving alone, according to some of us. Like Red Wood giants in Cali, for example. All the land cleared of wildlife to grow food for billions of humans is disturbing stuff at least to me as well. The planet is actually kinda... small. I've come to realise. I fully reject humanity's unearned superiority complex.

I acknowledge it's hard/impossible to be absolute in the vegetarian ideal given all the ramifications of industrial overpopulation and just casually participating in the society I was born into. Best I can do on this suffering planet, that I never consented to being born to live temporarily upon pointlessly, is to minimize (elimination is unrealistic) the suffering my life inflicts on others.

In other words, I don't owe anyone jack shit, not even Mommy Dearest. Yet I still stand by this moral position. Although I'd argue this is just who I am and always was. The justications put into words and labels applied came later. You'll notice I didn't condemn meat eating in this comment and that's quite deliberate. You are not me. I just explain my position when asked and it's up to others to adopt it or not.
