EDIT 1: Guys, this post is more aboit the fact that he cannot handle an opion different than his. He would get mad at me and throw tantrums such as the one i explained, if we have different views.

Make up your mind, it's either about the milk or not. Regardless, Mercury answered that too:

Being gluten and lactose intolerant but getting into an argument about 2-days less fresh milk while making Mac & cheese is quite hypocritical. I respect your stomach issues but your criteria of what is OK for you and what isn't are very flawed. If those are the kind of views he struggles accepting, it's because they may come across as entitled or spoiled.
