Stepping back and looking at a bigger picture, this is a cultural issue, and the left is notorious for forcing their agenda through the political process.
Darwinism is simply another tool of the left to use to deconstruct the Christian worldview that made this country and society great.
I would have to agree with your thought and add that it also has created a society that does not value human life as a greater life form that has dominion over every living thing and the elements of this great creation, we are just equals to it all.
