While I’ve certainly offended people, I try not to do so. My motivation is to convert those with weird ideas to a more reasonable approach, and offending them just polarized them and locks them into their beliefs..
I don’t mean that people should go out of their way to offend others. But when a person or group initiates the process by wanting to legislate what adults can say, do, own, eat or drink (cough, cough, Bloomberg!) then it is prudent for defenders of freedom and liberty to stand up to these people. For example, when they want to ban a book - read the book! It is exactly as Edmund Burke said, “All that is necessary for evil to triumph is for good men to do nothing.” Reading the banned book may offend and then polarize them, but they would have remained offended and polarized if nothing was done. And by not doing anything and not “offending” them, it is just one step closer to banning the book or whatever item or idea they want banned.
