If someone was born a Christian, but decides that God doesn't exist, Jesus was an ordinary human being, and that the Holy Spirit doesn't exist, and becomes an atheist, are they still perceived as Christians by Muslims?
Someone tweeted today
Atheists who've repeatedly insulted Christians draw a cartoon of Muhammad, so Muslims burn down churches. Go figure. http://www.bbc.co.uk/news/world-africa-30863159 …
and I wanted to know if the categories of "Christians" and "Atheists" make sense.
