Green - An environmentalist community

What you're describing in your last paragraph is virtue signaling, e.g publicly expressing some moral position to gain approval without actually following through on that moral position. That's not something to appreciate.

It is extremely commonplace in meat eater circles to virtue signal about ethical meat and then completely ignore that for the vast majority of consumption. This is a huge difference between vegans and meat eaters.

Vegans aren't virtue signaling, we actually have an understanding of what we believe to be a moral truth; it's wrong to kill and harm things for your own pleasure, whether that be taste pleasure, sexual pleasure, whatever, and we extend that as far as we're able to. We actively avoid food that purposefully necessitates killing and suffering.

Meat eaters advocate for some local maximum, like "I can't give up meat because it's too tasty, but I can at least avoid factory farming", and then they'll go to McDonalds 3 times a week once they're outside of a discussion with a vegan.

I'm much less frustrated with people who both advocate for and commit to some moral position. If someone abstains from all sources of fast food and factory farming meat and only goes out and handpicks cows to slaughter that they've known from birth, that's better. It's still wrong to kill something without it's consent, but at the very least if they're not virtue signaling they're at least not trying to deceive others.
