I don't live in the states, and this whole trigger warnings, safe-place and extreme sensitivity politically correct or otherwise that is being talked about all of a sudden was/is surprising to me. I didn't think The US is where something like this would take hold. I've spoken to a few people who experience universities in the US recently and heard very different views. One was that young americans are more political than they had ever been. Another thought it was us peering into the world of internet thought bubble generations, people who "grew up" within one. Another thought it was plain intolerance in a literal sense, very little ability to tolerate others that they find in any way offensive.. Not sure what to make of it. Curious.
