I mean, this sounds like something one would do on accident. Well, it more certainly sounds like something I would do. I can't tell you how many times I've absent-mindedly put something in the refrigerator that didn't necessarily belong there.
When it comes to personal preferences, I'm a fan of letting people eat their steak however they want it. However, I do think it makes sense to expand our culinary horizons and try it the way the chef feels it tastes best if we are open to that.
As for me, I appreciate the fact that some of these 'foods' aren't available or are out-and-out banned. In my opinion, some foods are potentially too dangerous and not worth the risk. Others are created or harvested in ways that seem so unethical, that consuming them seems beneath the dignity of otherwise caring, good-hearted people. Again, that's just my opinion.
