How is it remotely blocking someone's free speech or access to information when you politely and automatically tell them that the blatant racial slur they just used might offend someone?
It's also easy to see an automated approach leading to hilarious results with say tweets from African-American rappers.
Finally, maybe we can move past this "might offend someone" stance that offers 0% nuance?
Or that in the past insults differed therefore we should ignore today's.
Or that hypothetically something hilarious might happen so don't call out trolling harassment.
