I hear this complaint a lot and don't quite understand it. I don't think the goal in life is to not offend anyone. Just live your life as best you can and if others get offended that's OK. Learn from it if you want to, if it's nonsense ignore it. If someone injures you, sue them. If someone threatens you call the police. If someone stops being your friend get new friends. People are free to get as offended as they want and you're free to not let it bother you.
When there are laws passed that create penalties for offending someone then we have a problem. Until then the outrage about the outrage is just like the outrage itself.
