You saw someone standing up for something you believe in. And you didn’t like how they did it, but you saw other people cheer. So it must be OK.
So one day, while standing up for something you believe in, you go against your values by acting badly when you do it. But as badly as you act, those who agree with you still cheer. So it must be OK.
And while you were basking in the glow of being approved of by people willing to overlook your bad behavior because they agree with your message, someone else was watching and thinking, “It must be OK.”
