Re: If no seperation of church & state....
I don't see any reason for churches to avoid the topic of politics. They are under the rule of the same government as the people and their members, including the preachers vote also.
I also see every reason for the government to stay out of religion. Banning the pledge of allegiance in schools though is going too far. If some atheist parent objects to the pledge of allegiance stating 'one nation under God' fine - they can tell their kid not to say it but the kid should stand with the rest of the class out of respect for the country anyway.
