By that do you actually mean stereo typically ENTJ? Because PerC is full of them and they seem horribly unhealthy and God-awful obnoxious.
1.) lol Well how are you defining "obnoxious?" Because what constitutes "obnoxiousness" is relative. I'm talking more in the vein of being succinctly efficient, straight to the point/no bullshit/matter-of-fact, assertive, informed, knowledge driven, acerbically clever and witty, etc.... Personally, I'm not offended or bothered by any of the aforementioned traits; in fact, I'm refreshed by them. And FWIW, I've seen you display these very behaviors and you don't "vibe" inauthentic and all that "obnoxious" to me.
2.) Generally speaking, there will always be those who
genuinely embody the stereotypes (they tend to be rooted in some degree of truth) without putting on any additional airs because that's simply who they are, right or wrong, good or bad. But then there are those who seem to defy credulity in rather heavy handed and performative ways that, to me (a human bullshit detector and world class bullshitter > blame Fe), can come off a bit...forced...a la
routinely reciting cliched ENTJ "catchphrases"
while wearing the internet archetype like a cheap, ill made, designer knockoff they like to show off at almost every chance they get, whether anyone asked to see it or not. "Look at me in my (molting, faux) mink!! :hi: Ain't it majestic??" Not to mention, their often dubious, unsubstantiated claims and pronouncements concerning their ability to style others. Wanna further kill the fashion metaphor? The suit doesn't make the man, the man makes the suit. And even the real thing can look pretty fucking tacky if it isn't tailored properly. Ok, I'm done.
3.) And on PerC, "unhealthiness" is damn sure not restricted to type. Imposters, wannabes, and barelyhaveaclues of all types abound there.
