This is actually a pretty mild opposition to Christianity compared with a lot of the ‘stans.
There is a death penalty for any non-muslim (including Christians) who’d dare enter the segregated cities of Mecca and Medina.
That doesn’t seem so mild.
A friend of mine is a Baptist minister and he has been talking online with a Saudi convert for the past several years. The man is hoping to get out of the country soon, for he is afraid his family might be growing suspicious and would either turn him over to the religious police or deal with him themselves, and he wouldn’t survive either encounter.
