I only used the vatican to demonstrait my agreement with you that some atheists have pretty aggressive attitudes.
The church is what interfears with our politics. Particularly in the fields of education. Much more so than it does in your country. At my old school Britol Grammar we had to go to 'charter days' (and being ecclesiophobic doesn't help with that), we had to sing religiouse songs in assemblies, we where given speeches on variouse topics which always seemed to relate to God and his attitude towards this and that, had to say the lord's prayer etc. The surprising thing is most people there where atheist.
And also the church has not been all too pleased about Prince Charls' new wedding and they're making this very clear. He has decided to make it very low key and avoided church involvement wherever possible.
