Carson leaps over the line with his Islam comment per BBC News - Jon Sopel seems confused

This BBC report by Jon Sopel http://www.bbc.co.uk/news/world-us-canada-34311643 seems rather confused in part:

'... but what about the feelings of the three million Muslims who live in America? How is it going to feel to have a serious political figure, someone who aspires to lead this nation, essentially saying being Muslim is un-American?

These people who day in, day out serve their communities, support their families, enrich the lives of fellow citizens and make America the successful melting pot that it is. Kids who recite the pledge of allegiance in the morning at their schools and go to their mosque or church or synagogue in the evening at the weekend?'

Who are these Muslim children who visit church or synagogue at the weekend?
