It is said repeatedly by all "NTs" here that emotions and being upset is totally valid. Its part of being human and we all have emotions and feelings NT and NF. Being NT dont mean dismissal of emotions. And what LL is expressing from her husband is that he just wants to help her calm down and talk things out in a reasonable fashion, where he can actually be a contributor/helper and not just a object to rant at. It does not mean that he's dismissing her thoughts and emotions as invalid. Why would anyone do that? It would be silly and without regard for the other person.
