Remember, Christianity historically never met a religion it could not hate. And based on the evidence, that included all the other Christians. In every nation state where Christianity rose to power all the other religions were either destroyed. And until very recently that included all the other Chapters of Club Christian.
Islam historically has been far more tolerant of other religions, allowing them to continue, protecting their presence and respecting their traditions as long as they did not try to market their position as dominate and paid their taxes.
Judaism is the outlier since it did not practice recruiting or trying to market its position until fairly recently. Historically the only way to become a Jew was to be born as a Jew like Jesus.
