Loyalty means having someone’s back. It doesn’t mean holding the door while they do something wrong.

There is a version of loyalty that quietly turns into helping someone hurt themselves. Going along with it feels like support, and saying something feels like betrayal, which has the two exactly backwards. Being on a person’s side means being on the side of how they end up, not only how they feel this evening.

Say the awkward sentence once, plainly, with no lecture attached to it. You are not their supervisor and you do not have to repeat it. Then decide what you will and will not be part of, and hold that quietly.
