Unfortunately, it is also hard for those who like preaching Christianity in public places to refrain from making others listen to it also, whether they are Christians or not. That is the nature of Christina preaching. Likewise, it is hard for those who hate immorality to refrain from making other acting moral, whether they like it or not. That is the nature of morality policing. In the same vein, it is hard for those who enjoy violent sexual encounters to refrain from raping others, whether they like this kind of sex or not. That is the nature of rape.
Fortunately, many civilized people have learned that one person's freedom ends at another person's boundaries - but unfortunately many U.S.-ers are yet to learn that lesson.
