A country tag may be helpful here.

A person could argue he is creating a hostile work environment which could lead to trouble for the company. Typically going to HR is not wise, since they are not your friend and only look out for the companies best interest. This may be a case where HR should be involved to correct a manager that is clearly out of line. If you do go to HR get written and signed accounts from the others in your team, so it doesn't look like just one person is upset. A whole team of upset people has more power than a single person.

Regardless as to what action you take. I would highly suggest you brush up the CV/Resume and start looking for an exit.
