I fundamentally disagree that morality ethics and what should be tolerated is determined by group think. We all know the Natzis we’re wrong though their group think confirmed their ideology.

If we assume your statement though, that morality is determined by group think, who controls group think? The people with the loudest voice, the people who control media, the money, the famous. They heavily influence what the current group think mentality is and thereby determine what is moral. But this in my opinion is actually immoral, a horrible idea, and is intolerant of those who believe in absolute morality, namely the billions of religious people or maybe some agnostics who believe in absolute truth etc.

The reason why is that liberal progressive ideology is inescapably intolerant is that if promotes: accept everyone, tolerate every belief and religion and sexual orientation and self expression and perception of truth. But ultimately, nearly every belief system has some contradictions with others.

For example: to me someone with a coexist sticker isn’t being intolerant, because they are implying there can be multiple truths, and logic follows no absolute truth. I deem this intolerant to my belief that there is absolute truth.
