Kinda, but I think it's more of a question of "tact" from a US'ians point of view. There's a high priority placed on politeness (real or not), service, and ultimately obedience. While this conservatism may have it's roots in religion, the attitude permeates through the rest of the culture.

The US is a country of immigrants, and if you look at the history - immigrant groups tend to be pretty dang religious. Pilgrims and Puritans, Africans embraced Christianity with zeal because of their circumstances. Later waves: Irish & Italian Catholics, German Protestants, European Jews; all very religious. And modern immigrant groups, Latin Americans, Koreans, Indians, etc. can all be quite conservative. Religion and culture intertwine because people tend to hang out with their own in the beginning - and the place to find them is usually at a church/temple/whatev. I guess it's like the old lunch table theory, you'll prefer to hang out with people that you think are more like you.

[edit] And to extrapolate this to the current topic, the presenter's greatest sin in the eyes of many US'ians is not his gratuitous use of sexual imagery to convey a point, but his complete lack of tact when doing so.
