there are people who would go fight for these Christians. If I knew where to send a donation, I would be interested in helping them. I think it’s horrible to let our brothers in Christ be killed without even trying to defend them.
The Coptic Church of Egypt can use the help—to feed the families of those who were killed and re-build the churches burned by the fanatics a few years ago. Send what you can as a donation —you can find them on line.
