I guess they would. I never really gave it a thought before. Kind of irks me that so many of these mosques give money and support to terrorists and they get tax benefits.
This might get your goat. The mosques are primarily funded by Saudi Arabia, and they also fund adjoining schools. The textbooks used in the schools are Saudi published in English and Arabic, AND contain the same teachings that were used in Saudi funded schools in Gaza, the West Bank, Lebanon, and Pakistan to prepare young martyrs for Islam.
