A few examples of Islamic tolerance:
Saudia Arabia - Conversion by a Muslim to another religion is punishable by death. Bibles are illegal.
Yemen - Bans proselytizing by non-Muslims and forbids conversions. The Government does not allow the building of new non-Muslim places of worship
Kuwait - Registration and licensing of religious groups. Members of religions not sanctioned in the Koran may not build places of worship. Prohibits organized religious education for religions other than Islam
Egypt -Islam is the official state religion and primary source of legislation. Accordingly, religious practices that conflict with Islamic law are prohibited. Muslims may face legal problems if they convert to another faith. Requires non-Muslims to obtain what is now a presidential decree to build a place of worship
Alergia - The law prohibits public assembly for purposes of practicing a faith other than Islam. Non-Islamic proselytizing is illegal, and the Government restricts the importation of non-Islamic literature for widespread distribution.
