When someone is labeled NPD, what that means is that person has developed their own narcissism in a way that is now unhealthy. That is how your mother was, which is what you unknowingly learned how to develop as well. As I mentioned, it is "ok" to have your own strong opinions and likes and dislikes, but don't be like your mother and punish others for whatever they like or dislike, have or don't have, do or do not do.

Unfortunately, one of the things I have noticed that tends to happen a lot is how people tend to fall into the mindset of all ______'s are bad or wrong somehow and it really doesn't matter if it is a color, class, religion, political preference, culture, or sports team. And one can experience toxic behaviors in "all" groups too, almost like the pot calling the kettle black really. All one has to do is mingle in any "group" and announce their label as being different than the group to experience it. Or, one can say or appear to be the same and and witness it too.

Actually, a lot of experiments have been done with this too, and it's really interesting to see the results and what it really says about "human nature" as a whole.

So, the next time you get the urge to "troll" ask yourself what you are really a "slave" to and if it is actually productive at all or, as I mentioned are you just practicing the same thing your mother taught you to practice.
