Intolerance, of any kind, does not care about praticality. It's the infinite scream of a child, saying "but I don't like it!".
I have no proof, but I really wonder how much of the current resurgence of regressive ideologies (the correct word would be "conservative", but truth is this is a phenomena we can observe across all of the political spectrum) is the byproduct of the glorification of infantilization and nostalgia in our society.
"I want my old movies, I want my old games, I want my old white neighbourhood, I want my parents, I want my old society, I want my youth back".
