first you must admit there was no war of apostasy
NOW
in the quran allah says THERE IS NO COMPULSION IN RELIGION
in the quran there is NO command to kill apostate
some muslim say to kill apostate but they are WRONG
You still didn't answer the questions. I didn't ask what the quran says, I asked what you would expect to happen in the city of Mecca which is the shinning example of Islam to those who would dare to openly leave the religion of Islam. I also asked if you can think of any other religion where anyone who openly declared that they no longer believed and wouldn't practice the religion would have any concerns for their safety. If there were any concern then this forum wouldn't exist.
I am pretty sure that you are quite aware that imams (Muslim leaders) have issued fatwas for apostates. This is Muslim leadership directing that they should be killed.
I know of no priests, any other Christian church leader, any Jewish rabbis, any Buddhist priests or lamas, etc. that have issued a decree that those who leave their faiths should be killed.
You say, "some muslim say to kill apostate but they are WRONG" and I agree, they are wrong. But I don't see Islam being accepted as a "religion of peace" by other faiths or by atheists until those Muslims who also agree that it is wrong clean their own house and make their religion what they claim, contrary to evidence, it is.
But as to the war on apostasy, if Muslim religious leadership issuing decrees (fatwas) against apostates is considered a war on apostasy, then yes there is a war on apostasy - even if EVERY Muslim isn't involved. Every American wasn't involved in the war in Iraq (much less than 1% were) but there was certainly an American war in Iraq.
