Soy is quite allergenic, are not there notices about that on your packaging?

I'm talking about those chronically unable to apologize, and that don't seem able to learn here.

Some people have trouble separating actions and character, so admitting to committing a mistake becomes emotionally as admitting they're bad persons, and that threatens their sense of identity.

The emotional connection to their wrongdoing isn't guilt, but shame for who they are.

It's connected to low self esteem, in the worst cases to narcissism.

I think it's about identity and perception of self.

Accidents of ignorance are unavoidable, but accountability is important.
We all make mistakes, what we do about them includes taking responsibility and apologizing, otherwise we're bound to repeat them and spoil relationships.
