The dairy industry isn't the best to attack on animal cruelty. While there are bad actors within it, it's a small amount compared to it as a whole. Low stress cows produce noticeably better quality milk. This isn't a secret in the industry.
Wheat, soybean, avocados, palm oil and more are just as bad for the environment and animal life due to commercialization. Monoculture industrial farming is inherently unsustainable. High density growing of a single type of organism that requires outside resources to be brought it. Artificial fertilizer production isn't ecological either. The pest control required, and I'm not talking about bugs, I'm talking about rodents, birds, boar and deer, is pretty harmful for not just the animals, but for the regional ecosystem.
"Let's just make food more expensive for people! I decide what people should eat and when even though the purchasing power of the average individual is shrinking as is!" As an omnivore, I have to tell you, "slow down there Stalin". Then again, you're not wrong. You need less farmland if you starve enough people to death. Guess you're a fan of population control? Historically speaking, on average, anyone that advocates for the limiting of general food distribution to everyday people don't become well known as humanitarians or "good people".
You choose to be vegan, good for you. But don't pretend industrial farming of soy, peas and avocados don't have blood on their hands. The only vegans who can lay claim to the moral high ground are the ones that permaculture grow their own food. They get my respect, big time, since they're not virtue dieters.
