If someone's a mild jerk, saying "Hey, you were kind of being a jerk back there, seemed unnecessarily mean, knock it off" isn't being sensitive, it's asserting yourself. Sure, pick your battles, obviously. Nobody is suggesting violent jihad against the author.

"Hey, this reads as a bit racist to me" isn't really "crying to mommy/daddy", it's expressing an opinion on the text. Legislating what is and isn't an appropriate (ie, "not oversensitive") opinion on a text is counterproductive.
