Isn't it obvious? These White supremacists supporting Trump are obviously still pissed of at the fact that the great Liberal West stood up for freedom and democracy as Hitler invaded and annexed neighboring countries in Europe, when they would have preferred the Nazi Reich to go on and kill everyone who isn't a white heterosexual Christian. While the rest of us would condemn the inaction of Neville Chamberlain*, these guys see him as a role model: A weak-minded head of government who will let an authoritarian ruler have his way in Europe. That's why they like Trump so much, he fits the bill perfectly. With Trump at the top they can enjoy watching Putin bully, invade and annex neighboring countries and forfeit freedom and democracy. They happily forward his propaganda and join in with the trolls advancing his agenda online. God forbid that the great Liberal West stand strong and united in the defense of freedom and democracy! Not this time around! May authoritarian leadership, sexism, bigotry and hate prevail in the face of the devil spawn of liberalism!
*Not an entirely fair assessment of Mr Chamberlain as reality is more complex than the popular opinion about him would suggest, but as facts matter little to Trump supporters anyway I guess using him in this way is fine.
