Yeah. A Muslim is a follower is Islam. Most Muslims are Arabs. But “Muslim“ is not a race. Islam is not compatible with Christ.
Yes, which is why I said "Gentiles may convert to Judaism or Islam, but becoming a Christian/Messianic Jew or Muslim does require conversion or reformation from adherence to Mosaic or sharia law and superseding them with the Gospel and law of love". IOW, I hope that Islam will undergo a reformation like Judaism did led by Jesus and Paul and Roman Catholicism did led by Luther, which will require viewing Mohammed as needing to conform to (or be superseded by) the Gospel of Christ, like Moses and the Pope. Let us pray that will happen, however unlikely or miraculous it seems.
