A "religion" has opinions or worldviews on:
How life/universe began
How life/universe will end
Meaning or purpose to life
How we should act (ethics)
Is there a higher being/god
If there is a god, what is he like
What is the nature of man (good, bad, blank slate)
How we should relate to a higher being/god
I think that every person has opinions on these, even if it is to say that they don't know or don't care (that also reveals an underlying attitude on the subject). Everyone has a "religion." And I think theistic creation as well as strict naturalistic evolution has teachings or implications on these questions, and thus both are "religious."
The advantage of the secularist is that people usually don't recognize that the secularist beliefs are also "religious" (often because they deny it so vehemently, and because they don't worship in an organized way) and as a result, secularists are not constrained by the current interpretations of "separation of church and state." It's a nice little game that the secularists have going for themselves. They can promote their own "religious" beliefs, but censor Christians who hold opposing views.
The argument from design, an important part of the history of religion, wouldn't be ignored in my religious education classes, needless to say. The children would look at the spellbinding wonders of the living kingdoms and would consider Darwinism alongside the creationist alternatives and make up their own minds. I think the children would have no difficulty in making up their minds the right way if presented with the evidence. What worries me is not the question of equal time but that, as far as I can see, children in the United Kingdom and the United States are essentially given no time with evolution yet are taught creationism (whether at school, in church, or at home).
Of course what dawkins is aying is almost exactly opposite of what is the situation. Throughout school, kids are only and repeatedly exposed to evolution. I think that any proponent of ID or simply anyone who has seen some of the shortfalls of evolutionary theory would love to have Dawkins' proposal of equal time implemented.
Atheism is a religion because it claims to have the answers, that it is an absolute belief that there is no god.
Agnostism is accepting of religion in that agnostics admit they "don't know" if God exists or is He does, what the nature of that God is.
I don't accept the argument that they push for a secular (non-religious) society, they push for an Atheist society. Their no god God should not be institutionalized and forced down the throats of the citizens.
