I'm by no means an expert, but do not believe Coptic Chrisians in Egypt today are imprisoned for decade or lose their property like I saw in your comment. I believe a Copt now serves on Egypt's high court. I know they have existed from the 1st-2nd century AD, but don't know their entire history, but I don't believe the are persecuted under the law anymore. I don't doubt they may face personal persecution, but it's not state sanctioned, and from what I've read, their numbers may be much higher than the 10 mil reported. I have also personally met several, but did not notice a tattoo, but don't doubt you on it. The writings of the Desert Fathers and Mothers are some of the most inspiring to reflect upon to me personally.
