 Within those countries that openly advocate religious tolerance there remain debates as to the limits of tolerance.Some individuals and religious groups, for example, retain beliefs or practices which involve acts contrary to established law, such as the use of cannabis by members of the Rastafari movement, the religious use of eagle feathers by non-Native Americans (contrary to the eagle feather law, 50 CFR 22), or the practice of polygamy amongst the LDS Church in the 19th century.Religious freedom has developed partly due to the agreeable relationship between religious groups in its society.
