This comment does pop up every so often when the theory of evolution is discussed:
"Charles Darwin was racist, which means the theory of evolution is racist!"
Or
"The theory of evolution was used to justify slavery, which means that it's racist!"
(
Twice in the same thread too!)
One thing I always note with this sort of tactic, to simply discredit evolution by saying that Darwin was racist or that it was used in racist ways, is that... the people who use it really do just leave it at that and say nothing else.
ETA: Since I forgot to state: Charles Darwin may have been the person who came up with the idea for what became the modern theory of evolution, but that does not mean that his personal views dictate what the theory of evolution says. They were his own personal views and his own personal views alone. Racism has scientifically be shown to be an idiotic view and the theory of evolution has been one of the driving forces in showing that.
So my challenge is: without using the writing of Charles Darwin (which means his own works on The Origin of Species or any other books) or anything from the 19th century when slavery was practiced by the western nations, show me an example of the theory of evolution being racist.
I don't want people using it to justify racism. I want something from the theory of evolution that shows it being inherently racist.
