Of course you can judge a country based on one law. Would you enter a country that had a law stating that if your first name was jason that they had the right to execute you? Singapore has shown it has been willing to enforce caning people over graffiti, so obviously laws have consequences. If some customs official doesnt like the way I look, he can throw a dime bag of weed in my suitcase on entrance to the country and have my life ended. So yeah, laws have life and death consequences.
