I think people get arrogance & narcissism confused many times....there is definitely a difference.....but narcissists are definitely arrogant but not all arrogant people are narcissists.

There are a lot of misused terms. When I was trying to figure out what had been going on for 33 years in my marriage that had really been bothering me....if felt like emotional abuse....it felt like passive aggressive....but when I started looking into passive aggressive.....every person has times when they are passive aggressive & his behavior wasn't that way all the time. His arrogance was amazing at times & yet non-existent at others....I finally found out what the overall reason was for his behavior & it actually explained it all as it manifests itself in those different ways at different times. There are so many masks out there.....behaviors mask others as look alike. That's why it's so difficult to get an accurate diagnosis in the mental health community let alone the uneducated public getting it correct.....& sometimes it's a serious process of elimination.....I went through 7 years trying to figure out what I had been dealing with for the previous 33 years.

So many times dysfunction comes across as abuse also.....it's hard to accurately draw the lines & I don't think that professionals are always good at that either.
