You shouldn't protest against superiors even if it's unfair, right?

‌If you protest,
a good superior will reconsider once more,
but a wicked person
will rush at you to fight because they feel their authority has been infringed upon.
You have to phrase things carefully to avoid emotional confrontation,
because if a fight breaks out,
the organization and relevant agencies will treat it as a mutual dispute.
Or, they will side with the senior who has more experience and works well. (The "old-timer" gets dealt with at a ratio of about 9:1)
Unless you can phrase it indirectly, like:
"I am lacking in knowledge, so could you please double-check this for me?"
otherwise, just endure it.
