Discourse can only be had when one is open to listening to individuals different viewpoints and accepting differences. Unlike individualistic ideologies social justice define a person by a constantly expanding set of politically motivated unchosen groups organized as “oppressor” and “oppressed”, and it is actively opposed to discourse as it sees that as a mechanism for the powerful/dominant group to assert power over the less powerful group in a zero sum game.

I think its pretty clear at this point that social justice in the workplace lead to more conflict and resentment than its worth. It also makes excellent people doubt if they were hired due to a quota or because of expertise (or the reverse for other groups).

Yeah. Notice how the free speech absolutists are nowhere to be found here.

Pretty sure the free speech absolutists would say that private companies can have whatever rules they like on their platform.

Would, but aren't. Kind of curious in and of itself; usually they not only would but also are.
