Being a moderate Muslim is like being just a little bit pregnant....no such thing.
The Imams consistently state there is no such thing as a moderate Muslim.....that it’s a western invention and does not exist.
But they do acknowledge there are ‘Apostate Muslims’....which to an Islamic Muslim is one who has left Islam and no longer qualify as Muslim.....it is a conscious abandonment of Islam by a Muslim in word or through deed..as well as Muslims who have ‘questioned’ or denied any “fundamental tenet or creed” of Islam.
The vast majority of Islamic scholars have held that apostasy in Islam is ‘a crime punishable with the death penalty’, typically after a waiting period to allow the apostate time to repent and return to Islam. But others have varied opinions.
