While I generally agree. Id like to give a sort of counter argument, partly just for arguments sake. And politics aside. Most “minorities” as you’ve described above have probably suffered some form of cruelty, human-injustice, physical or mental harassment, etc.
And if someone is not of one of those specific “minorities,” it would be physically and perhaps virtually impossible to understand what that might feel like, respectively depending on the type of “minority. And I’m potentially speaking exclusively from the perspective of a non“minority” person.
Thus, my logic is, if I were to agree with the overall notion of your post, it could be attributed to the fact that I am a person who has not yet (or never will have) experienced what it is like to be a “minority.”
Now to touch upon the political correctness phenomenon or hyper-sensitivity, I feel like this is partly attributed to politics.
The other aspect, of this country (USA), that is engrained in politics, is law or the legal system. The ease of which one entity can sue another for something, that might have easily been avoided or settled otherwise is astounding. Which tends to eventually lead to it evolving into law.
And so, we have begun to see a trend of hyper-sensitive generations that may or may not be somehow connected to this over litigious society.
When you add politics into the equation everything gets skewed. When there might initially have been a sound, just, and impartial legal system, the politician will do whatever is necessary in order to sway things in their own favor.
Excuse the rant. But I think it’s always good to asses things as diplomatically and as objectively as possible.
