That Darwinism and Nazism are blood brothers is not what leftists should really worry about.No they're not. They're both totalitarian ideologies, but that's as far as they go. Here's a good analogy if you know Doctor Who. Socialists are Cybermen, Fascists are Daleks. One ideology wants to *assimilate* all groups under a homogenous culture. The other wants to *eliminate* all groups except the "master race".Nazism and socialism are identical twins merely separated at birth, which puts contemporary Democrats in a very bad light.
Okay, but I think foundation defines identity.
Nazism and socialism are identical in motivation and inspiration: a hateful, narcissistic desire to control others through the use of corruption and murder.
The rest is just details.
