By the way on a point of your previous thread about movies - I just saw Spectre last night. Argh ! Now even James Bond's villains are his family (basically) !
It is as if the imagination of Hollywood regarding conflict comes from watching "Baby Looney Tunes" - Tweety and Silvester were at it already at that age and were raised together...
Did you know that Hitler grew up with Winston Churchill ?
That Richard the Lionhearted was Saladin the Great's uncle?
That Lee and Grant were half-brothers?
That Napoleon and Wellington had the same mother?
That none of those things are true because this kind of thing does not happen in real life and conflict, moral or otherwise is NOT just a metaphorical extension of immediate family?
