Upper management doesn't think so:
If you're hesitant to say something controversial because you don't want it to be associated with your name, please create an alt account and say it.
If you want to say anything and not assiociate it with your name, then don't say it.
We must discuss even if we disagree. That's how we 're staying polite.
If I create an account to say something controversial, chances are that I will be offensive without any consequences.
