Nothing is like it used to be. PItting one group against another has become the order of the day, and we now have almost two full generations since that time 25 years ago that have learned you can’t trust anybody that doesn’t look like you, sound like you, have the same tastes in clothing/music/religion/whatever, like you. Divide and conquer – the order of the day. Or as Karl said 167 years ago, “In short, the Communists everywhere support every revolutionary movement against the existing social and political order of things. … They openly declare that their ends can be attained only by the forcible overthrow of all existing social conditions.”
And that is the bottom line.
