So what is wrong In limiting freedom for Muslims?
As I told you Sri Lanka, Myanmar, Cambodia and Bhutan are Buddhist countries and not secular states(at least not as secular as India and West). Bhutan is a strict Buddhist country where preaching other faith is prohibited. So it has the every right to limit freedom for Muslims.
In Muslim countries where Islam is given priority in the constitution or Islam is the state religion, minorites have restrictions too. In Pakistan Hindus cannot become president, in Malaysia non Muslim cannot become PM. Why don't you speak about them too?
Why do you want constitutional Buddhist countries to give equal rights when Islamic nations don't give equal rights?
