nstead of doing that, of course, they all got to reading a bunch of BS by Chuck Darwin and Fred Nietzsche, and we all know what happened.
Your bizare idea of European history has already been critiqued.
However, given the fact taht a lot of people have been killed in the 20th century, you haven't even tried to establish a connection with Darwin's work. You've just asserted one. Sorry, that doesn't cut the mustard.
You need to
demonstrate that Darwin's work was the cause. To do this you have to separate out the effects of better technology, coimmunications, social development, and a whole host of other factors.
I can't conceive of a way that it could be done. If you can do it, go for it.
But claiming that Darwin caused the many deaths after he lived is a
post hoc ergo propter hoc fallacy; for the Latin-challenged that means that just because B happened after A, that doesn't mean that A caused B.
