Sorry to continue this on and be the kind of “but…” person.
… But … A lot of vegans I know also try to reduce the amount of medicine they use cause sadly a lot of tablets have lactose in them. It’s genuinely one of the hardest things to deal with as a vegan, because it becomes the argument of do I better my life in spite of my ethics momentarily and it’s never an easy choice either way.
The way I see it is necessary suffering. There is no such thing as living without accidentally or implicitly causing suffering to someone, somewhere, so the logical response is harm reduction. Eating meat/cheese/eggs is not necessary. You won’t die or become ill if you stop. The calculation is not the same for medicine or food from agriculture generally.
