It’s okay to be angry/passions are good, actually
You’ll be judged for anything you do if you leave. If you’re angry, they’ll tell you to get over it and dismiss you as bitter. If you don’t care, they’ll say you’re in denial.
But anger is good and warranted.
One of the weirdest and unhealthiest things in orthodoxy is the teaching that we must overcome our passions. This encourages a kind of passivity. Feelings are suspect. This can appear wise because spiritual highs and lows are fleeting and meaningless. But in orthodox spirituality, reasonable suspicion of emotions becomes the teaching that all emotions are bad.
This encourages a kind of passivity. I think this is one reason why orthodoxy never developed any social teachings like the Catholics. In orthodoxy, people have no agency, things just happen to them.
Emotions are neither good nor bad but feeling emotions is good.
So anger at orthodoxy, at cult members, apologists, whatever is warranted. Orthodoxy is harmful. It is misogynistic, transphobic, and homophobic. It takes advantage of people. It’s okay, good even, to be angry at harmful things.
