Toxicity is not to be tolerated. Fight against it. Of course, the results may not be favourable or desirable. Fight regardless of all. If you do not fight, the toxic situation or people will further damage you by trying to trample you. You may even be shuddered within due to this act of theirs. So, stand up when anything toxic happens to speak against it. Or you can maintain peace because you know that toxic people will never change and are deliberately doing things because receiving a reaction makes them feel powerful enough to manipulate you. Tolerating toxicity does no make peace however, maybe in the short term but definitely not in the long term.
