That’s being suggested in Britain:
Humanists UK welcomed the recommendation that humanist beliefs and values be taught. In general, the commission’s conclusions were a “once-in-a-generation opportunity to save the academically serious teaching of religious and non-religious worldviews in our schools”, said Andrew Copson.
But the Catholic Education Service said the report was “not so much an attempt to improve RE as to fundamentally change its character … The quality of religious education is not improved by teaching less religion.”Harriet Sherwood, “Call for atheism to be included in religious education” at The Guardian
Surely the Catholic Education Service is missing the point. Atheism is a religious stance and an important one, given that many prominent people are atheists. Teaching beliefs other than atheists’ beliefs as “religion” means that the worldview on which atheists’ choices are based is going to be represented in a confusing way.
For example, many atheists don’t believe in free will. That doubtless influences what they advocate or think reasonable but if we can’t unpack it, we can’t talk about what it means.

Which side will atheists choose in the war on science? They need to re-evaluate their alliance with progressivism, which is doing science no favours.
