In many countries, the husband has a legal right to demand sex from his wife and rape in a marriage is not a crime either - in fact, even "civilized" countries such as Germany had it until recently, it took us Germans until 1998 to finally make marital rape a crime. One of the politicians in favor of keeping it legal actually ended up being our current Interior Minister but ah well, I digress... point is, the line between arranged and outright forced marriage is thin, very thin.
