Actually, people DO find things offensive rather arbitrarily. Worse yet, they are taught that they should increase the range of things (and people) they find offensive and unacceptable. Worst of all, today's generation has been taught there is no difference at all between being offended versus being injured, in every sense: physical, emotional, spiritual, etc. They're taught you must shut down and shut off anyone you dislike, and retreat to a "safe space" filled with people who think exactly alike. In this world, being a victim is heroic, weakness and fragility are strengths, and actual strength and resiliency are weakness. In this world, literally nothing you do matters. All that matters is conformity with rigid standards that emphasize anger and destruction as their primary values and moral imperatives. It is no wonder then, that terms like "microagressions" have sprouted up to further encourage the infantilizing of adult interactions with a psuedo-intellectual veneer. It's not so much what is or isn't offensive that is the problem anymore, but the fact that the left has sunk to the same depths as the right in their cynical disregard for the treasure that is human free thought. In their ends-justify-the-means attempts to control both the narrative and the power structures of society with absolute authority, the right and left have become mirrors of each other.
