The song is about cancel culture. To me at least. Think about it, people who strongly believe in whatever it is (faith, social Justice, politics, etc.), are willing to essentially be a martyr for their beliefs. They don’t care what others think. He calls someone a “righteous one” pretty much saying that they’re self righteous and they clearly aren’t any better than anyone else. So he’s basically brushing off anything someone says against his beliefs.
