I would be totally fine with them drawing their lines wherever if they let other people do the same, but many vegans will take the stance that consuming animal products or meat is always wrong, and never justified, no matter what. Many vegans actually would disagree that it is justified to eat animal products if a doctor recommended it, they’d say there are no nutrients found within those products which can’t be found in plants. They’d also be against eating gifted non-vegan food, many are against feeding cats a nonvegan diet too
Found it interesting to discover that the money here in the UK is made from animal parts - I think certain notes contain tallow? Definitely seems like it is impossible to fully exclude animal products from your daily life unless you go off the grid and try to be an entirely self sufficient vegan homesteader, which, while extremely difficult and likely dangerous is still an option open to those preaching a vegan lifestyle. Vegans often do not actually practise their philosophy as far as is practical and possible, they all draw the line somewhere so far as how willing they are to sacrifice their comfort and convenience. Like there are no fully vegan cars - the glue is animal based, even if you opt out of a leather interior. Public transport or taking a job you can walk to are alternatives in the UK if you actually cared about benefitting from animals as little as possible, but few vegans will make sacrifices which are actually inconvenient once you get down to the nitty gritty
Imo being a vegan so far as diet and basic lifestyle changes goes is fairly easy for some people (they don’t really like meat to begin with, know how to cook and enjoy it, no real health issues, disposable income) but the real test of how much they actually believe in these ideas is in if they consistently give up more niche forms of animal exploitation wherever they can
I think there’s nothing wrong with explaining your ideas and why you believe them to those willing to listen, but I can see why pushy activism for any cause can get annoying quickly. There are often Jehovah’s witnesses outside my local supermarket, for example, but they only give you a pamphlet if you specifically approach them
This is genius
