The ONLY place that is very strict is Utah because of the Mormons.
EagleSmack, it is not only Utah which is puritanical, there is the entire Bible Belt. Until recently sodomy was a crime in Texas, punishable by 10 years of imprisonment, until Supreme Court overturned it. And religious right has vowed to make sodomy a crime once again.
So the whole Bible Belt, Texas, Alabama (home of Selma and of the Ten Commandment judge Roy Moore), Mississippi (of the civil rights fame), Georgia and so on. Then there is the Midwest, which while not as a puritanical as the Bible Belt, is still very conservative.
There are only pockets of liberalism in USA, such as New York, California, Massachusetts etc. (and they are not really liberal by Canadian standards). Most of the country is very conservative, much more conservative than Canada or Europe.
That is also evident in the laws of the country. Homosexuals do not enjoy equal rights in USA, in many states, it is perfectly legal to throw a gay person out of his/her apartment, to fire him from a job just for being gay etc. Compare that to Canada, where gays can get married, same as heterosexuals. Incidentally, support for gay marriage runs at 35% in USA and at 60% in Canada.
In USA there is a big movement to ban abortion, and it would very likely have succeeded if McCain had won instead of Obama. In Canada, there are no laws regulating abortion.
USA has death penalty and the Bible Belt states, especially Texas execute several criminals every year. Canada has no death penalty. Prostitution is illegal except in some counties of Nevada. In Canada (and most of Europe), prostitution is legal.
In most issues, USA is very conservative and puritanical, much more so than Canada or Europe. Indeed, a liberal in USA will be considered a conservative in Canada. If Obama had to run for political office in Canada, he would have to run as a conservative, not as a leader of the Liberal party (and Obama wouldn’t’ get my vote, too conservative for my taste).
People are much more religious in USA compared to other countries, a much greater proportion of them attend church compared to Canada. I have also read statistics that interracial marriage is much more common in Canada than in USA.
By most measures, USA is a puritanical society.
