No, of course it is not. However, I've read some of the more bizarre complaints that the FCC has received about women showing any amount of flesh. There are some people who have serious issues with "nekkid" women in the US. No one seems to mind bloody violence, though.
no offence to Americans, but there are some people in your country with some seriously twisted morality...
you sell guns on the high street, but won't show a kid using a gun in a movie.
you've got a HUGE porn industry, but a woman can't flash a tit on TV
straight sex is okay in movies, but gay sex is heinous
sex gets movies higher ratings than violence
seriously: WTF?!
