Salam Alaykum, What I have mentioned before and will mention again is that the taste of the modern world will not agree with the 'milder' punishments put forth for apostasy by some of our 'Ulama, such as expulsion or permanent imprisonment. If we push the laws of apostasy to their extreme, we would see that the 'Ulama of Islam never thought of this matter as one were the apostate stays doing whatever he was doing previously and lives a normal life as if nothing had happened. This is what annoys the modern world-order the most about Islam, but we Muslims should be happy to emphasize that which distinguishes Islam from other systems of life out there in the world today.
