EG, offending somebody -- because it is so subjective -- should simply be that, they are offended. END OF STORY.
But right now being offended is as if you walked up to somebody and spit in their face, or worse punched them. And the actions being taken by those who "offend" are on par with actions you would take had somebody physically attacked another person.
It's come to a place now in society where even silence can be taken the wrong way. I've been accused of being politically incorrect over the years because I refuse to cotton to certain things the mainstream embraces, but I refuse to budge. My convictions are mine and mine alone. I don't try and change other people's convictions. But... if you stand for nothing, you fall for anything.
This is like a gay person saying "I'm not 'offended'. I'm sick and tired of anti-gay sentiment invading every aspect of life."
Your lack of introspection is showing through. You want to be able to say and act however you feel is appropriate — which is fine —, but you don't want other people to be able to call you out for what you say and do. This makes no sense, because those people are just saying and acting however they feel is appropriate — by calling you out.
You can't have your cake and eat it too.
People will judge you for what you say, the same way that you judge others for what they say.
What it seems here is that, while you judge others, you demand for the right to not be judged by others.
Why not just say, “this must be a big issue to them”? Why do you feel the need to prove that these things don’t offend you, and that thus they shouldn’t offend others?
