To my friend the convert to Coptic Orthodoxy–Clear and I were born into the protestant/evangelical branch of Christianity, but we are “Coptic” inasmuch as we are Egyptian and Christian (though some say that all Egyptians are Copts.. but I won’t touch that one with a hundred-foot-pole.)
Also, despite your conversion, you are not a Copt, but belong to the Coptic Orthodox faith. It’s a bloodline, not a religion. (So if I became an athiest, God forbid, then I will still be Copt.)
Some recommended reading if you’re interested:

http://www.xculturemag.com/bishai21.html (What? Protestant Copts?)
both by Sally Bishai, the champion of the young Coptic Protestant movement.
Good luck to you..
