Miltiades, I cannot find that thread to give you a reply so I have started a new post just for you, as you are the one that keeps asking the question.
You asked do I agree with apostasy? No I don't and there is nothing in the Quran that supports this.
If we look, in the light of all this, to apostasy, we will find that there is no decisive and definitive punishment in the Qur'an for an apostate, and that there is no single incident in the life of the Prophet to prove that he killed anyone for leaving Islam.
You said you studied Islam therefore you should have known the answer, I think you are asking the wrong people about Islam and getting the wrong answers.
JIHAD.
Although Islamic jihad is a Qur'anic concept, the Qur'an, in reality, is rarely consulted for understanding this concept. The widespread misunderstanding of jihad can only be attributed to an endemic neglect of the Qur'an, not only by non-Muslims, but by Muslims as well. The Qur'an has charged Muslims with the responsibility of educating others about its message and disseminating its teachings. Unfortunately, Muslims have had a big share in propagating the common misunderstanding that jihad is all about violence. Many Muslims think that "jihad" means "holy war." It is a sad but undeniable fact that many Muslims learn about Islamic practices and concepts, such as jihad, from secondary, often unreliable, sources. It is not uncommon even for cultural beliefs and narratives to be among those sources.
So my friend please stop misunderstanding ISLAM, there are good and bad in every religion, sadly you chose to look at the bad side of everything, take care be happy, enjoy what you have, relax take it easy and you will understand life far far better.
