How exactly does "subjective idealism" conflict with "natural selection"?
Where did I state that it did?
Darwin proposed that, with the natural variations that occur in populations, any trait that is beneficial would make that individual more likely to survive and pass on the trait to the next generation. This process of natural selection could result in completely new species. Darwin did not have an explanation for how the traits could be preserved over the succeeding generations. At the time, the prevailing theory of inheritance was that the traits of the parents were blended in the offspring. But this would mean that any beneficial trait would be diluted out of the population within a few generations. This is because most of the blending over the next generations would be with individuals that did not have the trait.
I'm well aware of Darwinian evolutionary theory. With that in mind, how are traits beneficial? Beneficial toward what? And how would your explanation escape teleology? Or is benefit merely a "consequence"?
No idea. But so far your only example of a non-religious ideology has been evolution, which is not an ideology.
Then what's the point of your argument?
It is not irrelevant at all. You seem to have a conception of public schools as places where kids sit like drones all day being force-fed information. It's not that way at all. In fact, I would argue that kids take in more information from their peers than they do from teachers.
None of which you state is verifiable; therefore, you cannot qualify the effects, and their extents, of which you speak. That is completely irrelevant.
This is so overly simplistic as to be useless. For one thing, it assumes religious families only get a dose of religious information once a week when they go to church. For another, it assume kids get no exposure whatsoever to religion on days they go to school. Both are ridiculous assumptions and render the entire exercise moot.
The assumptions are not ridiculous. I do not presume to know all Christians. However, surveys on the matter would indicate that church-going Christians go once-a-week predominantly. Feel free to verify any of my claims.
Species change over time. Traits are inherited. Species have common ancestors.
Once again, what facts about evolution do aforementioned inform?
