Visit any forum and the ENTJ section tends to have some of the most rude, condescending comments.
The big question is why do ENTJ's troll using psychological warfare?
The big answer of course is because they have so little control over their immediate environment that they need to go online and assert control by reducing another in that environment.
They commit acts of existential cannibalism because they do not admit that they are bullying but it is objectively clear. They will passive aggressively refer to you as a "retard," or a "moron," for not understanding that their "objectivity" is good for you.
In real life, the ENTJ will bully as well, but usually will run into some trouble by 20 and will have to soften and adjust. If the ENTJ still believes they are always objective even though humans are fallible and creatures of subjectivity then the ENTJ has an inflated and weak ego which may imply you are dealing with a legitimate narcissist.
This is a thread for asking an ENTJ why ENTJ's bully. You probably will not find another thread like this. You'll notice that if you go to another site such as reddit and ask this question in the ENTJ section you will be immediately flamed and told that the person in question is not a bully. False. Everyone has bullied at one point in their life. There are degrees of bullying of course and ENTJ's have a particular style of afflicting others when they are in their inferior mode of operation...that is when they think they are so objective they become tyrants and cruelly subjective and harm in their environment with false pretenses of "helping you."
