Note it down, bring it up to HR/your manager's manager.

Best case scenario, your manager is well-intentioned but is misinformed (or under-informed) about what is/isn't okay to say. Mild kerfuffle, not a big deal.

Worst case scenario, your manager is outright crap and the personnel around them is equally bad. (Aka the "you should really think about moving companies now" scenario.)

In either case, escalating is the way to resolve things.
