You overlook the fact that before Britain evolved into its current democratic state hundreds of people were murdered by the government in the name of religion. The current so-called "state religion" of the UK is superseded by the right to freedom of religion and as a result British citizens are free to believe in anything they like as was shown in the most recent study of religion in England and Wales.

As for China it is not a democracy as as a result restricts anything that might threaten the dictatorship that runs the country. Officially atheist BTW really means believe what the government tells you to believe. That sounds like a state religion to me.
France is a case all by itself. For the last few decades France has been desperately trying to preserve French culture by attempting to ban anything that seems to undermine it, such as the spread of English slang or foreign technical terms. As a result, the state religion in France is actually secularism - imposed by law if necessary.
I stand by what I said. Historically state religions have been highly oppressive. There are few if any exceptions.
I'd reply to this if I could understand it. Did you compose this post while drunk?
