Behind your question seems to be the idea that all places should be places for discussing the "ideas that matter". I don't think that is correct.

Work isn't a debating society. It isn't part of a political campaign. It's a place for efficiently producing things that people want. If it fails at that, society suffers, even if some really good debates happen. We have other places for those debates; we don't have other places for producing the things that society needs.

Work isn't a debating society but it is part of larger society, if we all go to work building gas chambers without any willingness to discuss the political implications of having all these damn gas chambers around, well..
