there is definitely healthy anger, and unhealthy anger.
Not having any anger, means not having any personal boundaries, which is what every cultish leader tries to do to passify people.
Having hate and rage is also unhealthy, and has been discussed in great detail.

perhaps a good continuum is this...
The culty leaders want you to be passive and do what you are told to do, voluntarily, of course.
The far right is about road rage and hate, not healthy.
But like Goldilocks, the middle is just right.
The New Wage culty groups want to make you think that healthy anger, assertiveness, is BAD. So they can mess with you.
Its like a dog, a healthy dog will bite you if you try to make trouble.
But with healthy boudaries, when some culty or LGAT recruiter tries to lure you in, you can tell them very strongly, to please Fuck Right Off, and have a nice day.
An assertive Fuck Off works wonders. Even a Scientology recruiter can't handle that one.
(of course, this is only for the real baddies...No Thanks works for normal people, but not for cults...they keep pushing).
Anybody can become angry, that is easy; but to be angry with the right person, and to the right degree, and at the right time, and for the right purpose, and in the right way, that is not within everybody's power, that is not easy.
