No offence, but that's exactly what my point is....If some sect or religion says having 11 wifes is OK or good for you....I totally disagree with it. For me or the society in which I live in, it is immoral to have more than one wife. And I feel it is easier to live my life peacefully without digging in books and having discussion with so called self proclaimed religious scholars to listen to a particular song.
All morals have been derived from religions. Some got "evolved" by human desires. Even in Islam there are "guidelines" for some aspects and there are "boundaries" for some aspects of life. It is really easy to diss Islam for "boundaries" without completely knowing the reason behind.
