people with this menatality

I want honest opinions on a certain communication mindset Some people constantly respond to conversations with negativity or dismissing most topics with criticism or get offended on literally everything like if you tell them their behaviour is not okay they'll be offended Even when someone shares personal thoughts or plans they tend to redirect the conversation into their own negative views or shut it down when disagreed with I am wondering if this kind of mindset usually comes from past hurt or insecurity
