God, grant me the serenity to accept the things I cannot change, Courage to change the things I can, And wisdom to know the difference. - Reinhold Niebuhr.
I really like that quote, as it embodies a part of my feelings on being offended. As such, I have reached a point in my life where very little offends me, in the 'modern' sense of the word (where I must rant and rave and rail against it) but rather, I find things that I find disturbing, or disgusting, and find myself realizing my edges, but not the need to alter the things that give me those feelings.
I think possibly that some of the reason for the rise of 'triggering' and 'SJW' (ugh, that phrase) and the like, is we have failed somehow to teach people how to deal with their emotions. "Being Offended" has become a catch all term with "I don't understand/like the feelings this makes me have."
I consider myself fortunate that it has only taken me this long in life to understand all this. There is a great deal about the world I disagree with to some degree or another, but I recognize that most of it will not be changed by my shouting, and the rest can be changed by gentle actions. Additionally, I have slowly learned to seek out viewpoints dissenting and polar from my own, and test own against them, discard what I find lacking, and adopt what is superior.
What worries me is that this habit is one that may be impossible to teach to people, but must be found on ones own. I hope that this worry is unfounded, and it can be taught, if only we remember how.
It is contrary to reasoning to say that there is a vacuum or space in which there is absolutely nothing. -- Descartes
