What has this question got to do with the utube video?
I think when I am feeling offended, it is often that someone has done something that my former socialization has dictated to be wrong or offensive. So when people do "offending" behaviors, it is mind-expanding.
Honestly, It is very hard to offend me. I get more offended when people respond to me telling me I'm wrong and determined to tell me I'm wrong with no evidence. Just pure emotion. But if someone feels I'm wrong and can calmly tell me so and use evidence, than we can sit down and enter a logical dialogue.
In general I'm honored by critical thinkers, but hurt by people who are more passionate than they are intelligent.
