is there actually non-vegan medication routinely used to manage the condition of patients suffering with measles? On threads about measles, people are normally saying things like "there is no treatment possible"!
It all sounds a bit "but what if you were on a desert island, alone except for a herd of pigs" to me.
Even if there is actually medication used to manage measles, I still don't see that it's such a trump card. Choosing to avoid animal products unless absolutely necessary for health is a fairly standard stance.
Girl: "this is against my principles"
Counsellor: "but if you do develop measles you might have to use animal products THEN"
Er, what? It's not actually as if she's guaranteed to catch measles, is it?
Disclaimer: vegan, brought up anti-vaccination, chose MMR for self when 18 and can make far better arguments for the MMR than that BECAUSE I am a vegan.
And I was parroting anti-vaccine nonsense when 15, and I was just as competent to make decisions about my body as the adults who parrot the same nonsense to me today about my decision to have the MMR for myself and my children. This is double standards.
