America gives its citizens the opportunity to get involved with the political process. You could, therefore, raise funds, begin awareness groups, demonstrate, be interviewed by the media, and countless other ideas to promote your own point of view. After all it's a free country !
The Bible on the other hand, gives Christians no such advice. All people (who are not elect of God) are the slaves of sin and of Satan. They will continue to live their lives in whatever way seems best in their own opinions.
