The tired old argument that we shouldn't allow Mosques because "most" Muslim countries do not allow churches has raised its head again. Let's put tghis to bed once and for all.
As I stated in another thread I openly condemn any country that doesn't allow people to worship freely.
Wikipedia lists 48 countries in the World that are predominately Muslim. It may not be the most reliable source in the world but it's the best I can find, so in alphabetical order, here they are with information about whether they do or sdon't have/allow churches.
Percentage rounded to nearest whole number.
Afghanistan: (99% muslim) I was wrong earlier, churches were banned under the Taliban, but the country does now have one small Catholic chapel. Christianity is now legal, but there just aren't many christians there.
Algeria: (99% Muslim) Christianity legal. Churches exist.
Azerbaijan: (93% Muslim) Christianty allowed. A new Catholic church was built in the capital as recently as 2002. It replaced the old church which was destroyed, not by Muslims, but by Communists when it was a part of the Soviet Union. There are also several other Christian denominations (including the Church of Armenia) which worship openly in Azerbaijan.
Bahrain: (81% Muslim) Churches allowed.
Bangladesh: (90% Muslim) Churches allowed.
Brunei: (67% Muslim) Christians are free to worship, the Catholic Church has three churches in the capital and two in other towns. Bear in mind Brunei is a tiny country. Brunei has its own Catholic bishop.
Burkino Faso: (50% Muslim) BF has total religious freedom. There are several churches in the capital. I've been concentrating too much on catholic churches, so here's a Baptist evangelical one.
Chad: (54% Muslim) Approximately 30% of Chad's population are Christian. Christians worship openly. I can't find a photo because a google image search for Chad Church comes up with loads of St Chad's!
Comoros: (98-99% Muslim, sites vary) The Union of the Comoros is a tiny African state of 3 islands. It's population is 98-99% Muslim, there are less than 400 Christians. Despite that it has 3 Churches (2 catholic, one protestant) who carry out their business unheeded. Christianity was briefly banned following a coup in 1999, however, religious freedom was reinstated in a new constitution in 2001.
Djibouti: (94% Muslim) The population here is 94% Muslim, 6% Christian. Christians worship freely with no restraints.
Egypt: (90% Muslim) Churches allowed. The Pope of the Coptic Church resides in Egypt.
Eritrea: (60% Muslim) A relatively new state, gaining independence from Ethiopia in 1993. There is freedom to worship in Eritrea, but any religion has to be registered and recognised by the government, currently three Christian denominations (including Catholics) are recognised and worship openly with their own churches.
Guinea: (85% Muslim) 10% Christian. All Christian denominations are recognised by the government and are free to worship.
Indonesia: (86% Muslim) Christians are free to worship.
Iran: (98% Muslim) Christians are, maybe surprisingly, allowed to worship.
Iraq: (97% Muslim) Likewise.
Jordan: (95% Muslim) The Coptic church is partciularly big in Jordan.
Kazakhstan: (57% Muslim) The Russian Orthodox Church is big here. Kazakh culture is built on tolerance and once it gained independence from the USSR hundreds of mosques, churches and synagogues were built relatively quickly.
Kosovo: (90% Muslim) According to wikipedia, Kosovo is "densely covered" with Serb orthodox churches and monastries.
Kuwait: (85% muslim) Churches allowed.
Kyrgyzstan: (75% Muslim) The Russian Orthodox Church is big here.
Lebanon (60% Muslim) I was surprised that figure was so low! Anyway, there are several churches here. 39% of Lebanese are Christian and worship freely. Here's one of the oldest:
