Well, you should do a better job reading the entire thread as I posted an article explaining why apostasy is punished in Islam.

In all 4 schools of jurisprudence, hanafi, hanbali, maliki and shafi'i the scholars agree on this subject. Apostates should be punished with death.

There is no classic opinion among scholars saying that this practice is contradictory to Quranic verses. This is only an opinion some funny people have developed recently who solely rely on english translation of quran and like to see Islam being changed to something suiting the Western secular lifestyle and beliefs.

They want Islam to match the ideas of John Stuart Mill.
