As a vegan:
A. wtf, why would this warrant banning? At most it should have been a warning to use a less hostile tone? B. Why is it absurd? Should I be okay with a burglary in my neighborhood when there are wars going on somewhere else? Your equivocating meat consumption with wasteful transport suggests to me a fundamental misunderstanding of the motivations of veganism. No sentient, feeling creature has to suffer and die for someone to take a jet ride, but they do for me to eat a hamburger. I think the private jetters should feel guilty too, but for different reasons. In any case, how do you feel about dog meat?
Regarding availability and cost efficiency: shipping soybeans from Kansas fields to a cattle ranch in Nebraska and then the beef to a grocer in Idaho is less efficient than shipping soybeans from Kansas to the grocer (obviously, this is an oversimplification). Not to mention that animals aren’t perfect energy converters, reducing efficiency further. I’m not arguing that it’d be easy for the whole world to convert to veganism, but in most developed countries it’d actually be more efficient and cost effective (at the society level; not necessarily for all individuals) for most people not to eat meat. Especially if subsidies for animal agriculture were redirected to plant agriculture.
In any case, who’s actually “ramming” ideology? As a casual lemmy user, I do see a surpising number of discussions on the matter of veganism, but most of what I’ve seen has been pretty civil. I do recall a lot of self-defeating thoughtless toxicity from vegans in the vegan subreddits, but I haven’t witnessed it myself on lemmy.
Also consider a healthcare career. As a teenager, I wanted to do computer science/engineering, and sometimes I do wish I had stayed on that track. But now, as a nurse, I could get a job in any state in the US by tomorrow. I dare you to try to find a hospital that doesn’t have open nursing positions. Even when the economy goes down, people still get sick. Even if society collapses, the knowledge/skills will be useful.
And if you don’t want to change diapers or deal with blood, there are still options; I’m in psychiatry and rarely have to deal with either.
