Honestly, it's a massive win for cultural progress that we have even made the suffering of people with a different skin color intelligible to most people.
Intelligibility of the suffering of other species will probably take a considerably longer amount of time.
The circle of moral consideration in the Western world started generally with land-owning white men, then (still generally speaking) widened to include white men without land, then women, non-white people, etc. The circle of moral consideration is slowly starting to cover non-human animals, though it will take hundreds of years before they are truly protected.
The folks who say they do not care about animals join the company of everyone who has historically opposed the widening of that circle, the people who stood against granting basic rights and basic consideration to those who enjoy them today.
That being said, it is a huge proposition to proclaim you're on the right side of history, and that others who aren't should either reconsider or live to regret it. Especially when the change you champion will only happen when those that make money from meat no longer do. I'll sooner bet on the grass turning purple.
No matter how much money someone makes from owning a slaughterhouse, they can't make me eat something I don't want to eat.
We can all think of a couple historical instances of radical social change which necessitated short-term economic sacrifices and paradigm shifts. Yet, the grass isn't purple.
I don't see value in pandering to hypothetical future moralists. If they one day resurrect my corpse and torture me for eternity as punishment for eating animals, maybe then I'll care. Best case scenario, this comment may provide the same vacant sense of superiority that quotes from dead racists do for us; worst case, society regresses to bigotry and our current social morality is derided as a failed experiment, and you and I will share a cell in the cybernetic hell the 7th Reich make for resurrected wrong-thinkers.
I still like chops.
