:::::I agree - I have no inherent objection to such an article on the concept of state atheism. I think this sounds a good idea - we move the criticism material to the criticism article, and keep this article on basic neutral facts, modelled alongside state religion? I have no problem with mentioning supression of other religions, but here it is listed as "typically" part of the lead definition, and covered extensively, giving WP:UNDUE weight, compared with state religion where suppression of other religions is not mentioned at all, as far as I can see. Nor does that article have any of the criticisms that people might make of the concept of state religion, or religion in general (and I think it's right for the article not to cover it, as we cover it better elsewhere).
