Yeah, absolutely. The if you had to argument is one I often get hit with. It's dumb as fuck, but I'm so use to answering it off the bat right now.

Like, I had a kid who was failing to thrive. They couldn't breast feed, and refused all vegan options we offered in formula. They'd dropped weight significantly, and it was scary as heck. At that point, if gave that kid non vegan formula.

This is the closest I've ever come to an "if you had to" argument.
