I love this quote, and I couldn’t have said it better myself.
A friend criticized the quote, pointing out that it should have mentioned exceptions: Some protesters were indeed anti-police, for instance.
Ironically, that was the point of the original quote, wasn’t it? You shouldn’t take the exceptions (racist police) to imply that all police are bad any more than you should take the exception (violent protesters) to imply that all protesters are bad.
If we have to add “there are always exceptions” to everything we say our conversations will be unwieldy and ultimately not very informative. (Of course, not every conversation. There are always exceptions.)
