I’m a bit confused if I watched the same thing as OP and you. I don’t think those comments are from him, but rather random people responding to his video? The video seemed like an argument that pure self-interest is self defeating, and on the importance of solidarity, in response to someone saying that supporting blind access is virtue signaling. But with a clickbaity and a bit misleading title (note apostrophe position in Redditor’s vs Redditors’)
