I see another problem: If you can't be openly sexist (or whatever you call it), you will still be in secret.
This low standard of discourse hurts everyone.
Employees at work: shouldn't be discussing issues that distract them; shouldn't be socializing with each other because work and personal life should obviously be separate; they should just keep their heads down and keep working.
There's no doubting that all recent controvertial topics have led to the ideas that: divide up society into individuals afraid to express their opinions; human expression is not an important goal and that the workspace where you spend most of your time is ONLY to do the job like a machine.
