Why keep playing their game and giving tacit approval to the awful things they do by failing to take a stand? Why show them that they can get away with anything they want and you'll keep trying to appease them like an abuse victim? You took a stand when you went in, why not take one when you leave? Why do people continue to live without true freedom because they let fear of rejection keep them from writing a simple letter, playing all types of mental games to justify their inaction?
Take whatever stand you want. To thine own self be true while the cowards judge you.
