The islamists of Saudi are one of the most radical of them. It is more correctly known as Wahhabism although most Wahhabi refuse to be acknowledge with that name. Right now the biggest contributor to the mosques in the western world are the Saudi wahhabists.
Yes, I heard besides no churches being allowed in Saudi Arabia, Christians (mostly foreign workers) are not even allowed to have Bible studies!! I read an article where a Christian even said they were hesitant about what they said on the phone.
Several months ago, Christian Aid reported a pastor from India being thrown in the Saudi prison.....he had been invited by a group of Indians working in Saudi Arabia and was on his way to a Bible study with them. The "religious police" arrested him enroute. I haven't heard any update on this particular brother. I've also read that the Saudi prison is so extremely crowded, the prisoners are just packed in. Also, very little water is available to them.
For awhile I had posted at an Islamic forum where there were mainly Middle Eastern and Saudi Muslims.....they definitely had a one-track mindset, compared to some Muslims that were Asian at another website.
