If you want to get rid of conventional religions, point out that abortion, officially considered murder by Abrahamic religions, made more kills than the political murders of Hitler, Stalin, Mao and Pol Pot combined, and that Hitler, Stalin, Mao and Pol Pot were more or less Pro-Life, or at least restricted abortion. On the other hand, Orthodox Jews have a lot of influence in Israel, yet they do not even ban abortion for Jews. Muslims commit a lot of terror attacks, but NEVER target abortion clinics in the West.
This makes all the Muslim whining about the “immorality” in the West sheer hypocrisy. They also ally with the very same Leftists that promote the “immorality” in the West. This is outlined by Dinesh D’Souza, in his wonderful book “The enemy within”.
Jews and Muslims only use abortion as a stick to hit others with, when it comes to circumcision, or the stoning of adulterers, and to increase their own birthrates. When others complain about that, Muslims say the non-Muslims should have large families themselves. But then they overlook that Muslim children harass non-Muslim children, forcing non-Muslims to expensive private schools, limiting the number of children they can have. Muslims can say the harassment was deserved, possibly, but then they can’t say non-Muslims should have large families.
