Righteous indignation is Scriptural brother.
Saying calm down is not standing for what's right, it's being condescending and dismissive of an injustice.
You can produce better and real answers when you are calm.
He says, “Be still, and know that I am God." Psalm 46:10a
It usually goes unnoticed.
But, being still when it is applicable is doing a good work.
Dong nothing in that case?
In God'[s eyes? Is trusting Him and doing something.
More often than not, its not righteous indignation.
Its more likely frustration we experience at a time God is showing us we have more to learn and to yet understand.
There is much more in riches to know and understand than many realize. Few find it..
grace and peace ...........
