I've had a certain debate a few times where you might say we argue over the "semantics" of the meat industry.
I am what you would call a vegetarian. While vegetarians won't eat things that caused harm to produce, a vegan won't eat anything having to do with an animal. A lot of those who would fall under the latter category hate us because they say anything that remotely resembles someone enjoying an animal product is supporting the meat industry which then kills animals, which means merely eating an animal product makes someone a murderer.
Meanwhile, there's this concept many call piracy. It's the idea that, as the meme proverbially puts it, "you can download a car". The idea here, which I say in the way I do because there's still an ongoing debate about it, is that it affects nobody. But then there's the whole industry thing I mentioned. People on the other side of the debate often say "well what about the industry". I'm not sure where on the scale in this topic you might put me, but I feel like there's a glaring contradiction here. When it comes to animals, people think of the industry, but otherwise that's not a factor.
My question is... why?
I also don't understand the comparison to piracy but I think being a vegetarian is definitely more ethical than being an omnivore as long as you don't overcompensate meat with other animal products. If you stop eating chicken and in exchange start to eat an additional 3 eggs a day, that's probably worse for animals and nature.
If you just cut back on meat and replace it with vegan alternatives while eating the same amount of cheese, eggs etc. as before it DOES have a positive impact and we should appeciate one's efforts.
Hell, even flexitarians have a positive impact. Right now, there's around 90% omnivores worldwide. If all these omnivores reduced their consumption of animal products by let's say 20%, it would have a far bigger impact than another 2% going full blown vegan.
Furthermore, it can be tough to go vegan all of a sudden. It takes time to change your diet, learn about healthy protein sources, essential nutrients and stuff. Going flexitarian first, then vegetarian and potentially vegan allows you to take one step at a time.
Also being vegan is not where it ends in terms of caring for the environment. You can keep reducing your personal footprint indefinitely. No more flights, no car, less electricity, less shopping. Everything helps. And everyone should try to contribute in the way that feels the most manageable for your personal circumstances.
