Your argument that most vegans don't grow their own food in no way makes veganism less ethical and is a complete red herring. I won't waste my time on it.

Your entire argument about most people working for slave wages to raise crops is both a red herring AND undercuts your criticism of veganism.

1/3 of all grain worldwide is fed to livestock. 0% of that is being used to feed vegans. The rainforests are being cut down almost exclusively to create grazing land for cattle and to grow (mostly) feed for livestock. If the world were vegan, we could all eat grains grown on less farmland than we now have. No need to clear any rainforest.

No additional animal habitats would be destroyed. However many animals are killed in harvesting, it is an order of magnitude fewer when those crops aren't being fed to animals bred to be slaughtered for food.

Maybe you had multiple responses, but your response that I replied to said nothing about destroying the meat industry or factory farming.

The "ideals" of veganism are not universally agreed, so I won't respond to your additional strawman attack on what you claim as hypocrisy to those "ideals."

The definition of veganism I know and follow is to do the least harm to animals as possible. As I noted in my first response, not everyone has can go vegan. What is "possible" in Paris, France is not necessarily possible in Paris, Texas. But if you can go vegan, or just reduce the amount of meat and dairy you consume, of course it is better- morally, ethically, and environmentally. You will do less harm to animals.
