Not in "The 21st Century?

Those many who unhesitatingly talk about how this and that cannot be possible in "the 21st century", are really unconscious and/or ignorant of the cultural and social realities that the date -- in a post--Christian, post-European? post-"Western"... -- time, has little reality of meaning. Most of that was destroyed in the devastations of "the 20th century".
Such speakers are like somnambulists, talking in their waking sleep.
