I agree with this 100%.
What I have a problem with is when offended people conjure up outrage from their own misinterpretation of an action, a statement, a word, etc.
It reminds me of an incident in D.C. several years ago when a white aide to the black mayor used the word " niggardly" to describe someone. A black staffer took offense to the word, mistakenly correlating it to the word nigger. It became a mini scandal and the mayor forced the white guy to resign. When clearer thinking eventually prevailed, the guy was rehired, but it's this kind of stupidity that can lead to blind groupthink which can be very destructive and also make it harder for a legitimate claim of racism be heard amongst the din.
