Wizard, Asia includes India (mainly Hindu and Sikh); China (mainly Tao and Buddhist); Sikkim (Buddhist) and many other non-Muslim countries.
Asia excludes the following countries that have a Muslim majority: Nigeria, Sudan, Senegal, Somalia, Chad, Lebanon, Gambia (these are only some of the African countries that have a Muslim majority)
Nor are Arab countries in Asia - Turkey, Morocco, Saudi, Iraq, Qatar, Bahrain, Kuwait.
Nor the European countries such as Albania.
So no, the majority of Muslims are not Asian. And the majority of Asians are not Muslims.
