You made the right choice.  I wish someone had convinced me to avoid my marriage.  My last wife wasn&#x27;t a really strong anti-vaxxer (we never had kids, so it never was a big issue), but she did buy into it and closely related, she was really big into &quot;alternative medicine&quot;.  She spent a ridiculous amount of money on that crap, and of course that was one of the big factors that lead to our marriage failing.<p>I agree with the other guy though about you conflating things.  You&#x27;re right that being anti-vax and using alternative medicine is largely about fear (which she has problems with in many other areas too: she&#x27;s afraid of terrorists, she&#x27;s afraid of illegals, I could go on and on), but veganism, as far as I can tell, is not about fear, it&#x27;s about an extreme philosophical position where those people don&#x27;t want to hurt or abuse animals in any way. (The problem with the position, of course, is it&#x27;s just not very practical.)  I don&#x27;t see the two as the same at all; my wife wasn&#x27;t into veganism at all.  She was into organic stuff though, which of course is based on fear, though not completely irrational as a lot of our food in this country is of shitty quality and many farming practices are questionable (for instance, giving livestock tons of antibiotics even when they don&#x27;t need it, which is causing more antibiotic-resistant bacteria to arise).<p>If you&#x27;re in the position of dating someone who you might have kids with, and she&#x27;s anti-vax, I recommend getting out ASAP.  You&#x27;re going to end up having horrible fights over it.  If you&#x27;re past the age of having kids, it&#x27;s less of an issue, but it&#x27;s still a good indicator of a very different worldview, so I recommend avoiding those people.
