The mentality of evolution, "only the strong survive", "kill or be killed" is sort of disturbing.
That's not the mentality of evolution, if evolution can even be said to have a "mentality."
A harsh way of seeing it, don't you think?
That the hard work of competition is the only way to achieve real reward? What's harsh about that? Isn't that the sort of rugged, can-do individualism that's so quintessentially American?
The alternative is the "everybody wins all the time, you get everything for free" mentality that religious conservatives find so repellant and "liberal." To the degree that evolution suggests that hard work is necessary for survival and gain, I would think that religious conservatives would be behind it. Except for the whole "contradicts the Bible" thing.
