I'm convinced there's a growing group of people who are so insecure they feel the need to try to improve their self confidence by being more sensitive than everyone else. It started with decent people feeling better about themselves for not being like horrible people, but once society largely eradicated those horrible people, they had to find someone else to be better than. Over the past decade they've just kept one upping each other in a race to be the most culturally/ethnically/lifestyle sensitive, so it's gotten to absurd levels. But if someone's self worth and self image is based on being more progressive or sensitive than others, they're not going to ever be satisfied with any level of sensitivity.
