My question was why do you think Protestants (Protest-ants) left Catholicism?<quoted text>
Then you have a problem with a very small slice of Islam, and no problem with the rest of Islam. Right?
Or do you have a double standard about other religions?
Islam can't split up or they will be killed by each other. Their family members must, at least 'pretend', to worship, or the neighbors will attack the father if he doesn't punish whoever doesn't worship their precious mohammed & allah. Most of them worship out of fear of being killed.
