I can understand why somebody would say something like that, and how it can indeed be true in specific contexts. Yet, that's the key word, isn't it? CONTEXT. If comedians provide context in an effective way, they're contributing to a much-needed dialogue. If they're using it as an excuse to make broad, sweeping generalizations with no tangible solutions behind them, then what does that do for the public discourse? Or, alternately, if they're trying to weaponize group identity to gain cheap laughs for themselves, that's exploitative. It's clearly "shit-stirring," and their comedian status shouldn't automatically absolve them of any culpability for that.
Chalking up someone else's very existence to that narrow binary *is* bigoted. It's essentially saying that members of a specific group don't deserve to be heard, served, or respected due to that attribute per se.
When you couple that with hero worship (i.e. "celebrity privilege," or iconism), that's a dangerous combination.
