Are all narcissist dangerous

of course they are all humans are dangerous but just because they can hurt you doesn't mean they will. and some people are hurt by things that don't hurt others for example you can say anything true about me and I won't get mad but if you lie about me I'll hack your email and suddenly on every social network you use your new idle will be Hitler and you'll be a homosexual or if you already are you'll be a hetero sexual. your boss will be asking you why you emailed him gay porn and your entire life will fall apart. I hope you found this as humorous as I did while typing it.
