I mentioned that twice. Also you don't address the rest.
On the life choices, again, this is stuff that we all do in my country because we're poor. We all recycle, we don't have fast fashion chains, we don't constantly buy phones, etc. I grew up buying things from "dispensaries" i.e. you take a bottle to get refills, and you pay for the content because it's cheaper.
I'm not disagreeing that you can't do anything to be slightly more green. My point is that the reason vegans get mocked is because instead of trying to propose solutions that help other people they make assumptions about other people's (especially the poor) lifestyles instead of trying to work with them to find a good, sustainable solution.
