Syria, Lebanon, Iraq were once mostly Christian countries. Then one day they let in one Muslim.

Before it was Pakistan, the population that lived in that area were once mostly Hindu. Then one day they let in one Muslim.

Indonesians once practiced Christianity, Hinduism, Buddhism, and Confucianism. Then one day they let in one Muslim and today it is the most populous Muslim country in the world.

The peoples of Malaysia before the 15th century could practice whatever they wanted, Buddhism, Hinduism, or their native Animism. Then one day they let in one Muslim and so today, if you are a native Malay, by Law you must be Muslim, there is no choice [Article 160 of the Constitution of Malaysia] if you want to remain a Malay citizen. Malays who convert out of Islam are no longer considered Malay under the law and lose their favored Bumiputra privileges.

So you may ask, "What's the big deal" So you lose your citizenship, at least you are allowed to convert out of Islam." But that's a joke too:

Western Resistance Blog, 24 Jan 2006, Malaysia: Muslim Court Allows Apostate To Be Buried As Buddhist
The case of people being classed as Muslims is complicated by the issue of apostasy. Cases where people have tried to leave Islam have to receive permission from an Islamic court, and such permission is universally denied. The Straits Times from Sept 20 2005 stated that a sharia court has never granted permission for a Malaysian Muslim to convert out of Islam.

You will find various travel websites that post Muslim Jokes like this: "Malaysia's official religion is Islam, but the freedom of religion is guaranteed by the constitution." Yes, it is true that if you are not a Malay you can practice whatever religion you like, with a few minor restrictions:

Do not marry a Muslim person in which case you are required to become a Muslim also.

If Christian, do not try to construct a new church.

You cannot talk to any Muslim about your religion; Article 11(4) of the Federal Constitution of Malaysia expressly prohibits the propagation of any religion other than Islam to Muslims.

You can celebrate Christmas as long as you don't mention mention Jesus Christ.

If you are Hindu your temples will be destroyed:
On October 30, 2007 the 100-year-old Maha Mariamman Temple in Padang Jawa was demolished by Malaysian authorities [Hindu American Foundation].
On April 21, 2006, the centuries old Malaimel Sri Selva Kaliamman Temple in Kuala Lumpur was reduced to rubble after the city government sent in bulldozers obstensibly because of a "violation of construction laws" [Malaysiakini].
On May 11, 2006, armed city hall officers from Kuala Lumpur forcefully demolished part of a 90-year-old suburban temple that serves more than 3,000 Hindus [Financial Express].

But given the rules that once a Malay always a Muslim, that marrying a Muslim means you must convert also, that other religions are in fact discriminated against, that new churches or temples cannot be constructed and old ones are demolished, then it's only a matter of time before Malaysia becomes infested with 90% or more Muslims just as in:

Pakistan 97%
Bangladesh 90%
Egypt 90%
Turkey 99%
Iran 98%
Morocco 99%
