I suspect that just because there is a minority present doesn't mean that it is always tolerated; especially if an American is involved overseas. I believe tolerance changes with the winds (or whims) of time as it were.
My friend's conviction was down the lines of evangelizing and disturbing the peace. He was in Egypt for combination work and vacation and while preparing to leave was overheard commenting to someone he had meet on being a Christian and was reported to security. He got detained, questioned, beat up a little, and tossed in jail. He was later tried, found guilty and left in prison. The US government couldn't, or wouldn't, get him out. Sad story really.
