We have embarrassments such as the “Flat Earth Society” that cause a certain amount of fidgeting among Christians who fear being discredited by whack-a-doo splinter factions. As an avowed apostate I don’t lose much sleep over such nagging questions. Of the top 500 universities around the world, not one is Muslim.
At this point I introduce the rather radical concept of good and bad, better and worse. An even more radical is the idea that these concepts be applied to a look at different cultures. Christianity, for example is far superior to Islam. Islam calls for a return to the good old days of the seventh century. Gives bad advise on hygiene, medicine, male/female relationships, culture etc. the list goes on ad-infinitum. Very few actual spiritual disciplines are mentioned in the Koran, most of the text is devoted to sundry daily behaviors that impart no other spiritual dictum than prohibition of various unacceptable behaviors. It’s a mans religion! You can beat your wife, rape captive women after you’ve killed their husband (Mohammad did this one), kill your family for dishonors real or imagined. Or, if your an Islamic male you can do anything you want to anyone of lower status than you, (males younger than you and women of any type). Baby if your a guy, this Buds for you!
Of course you don’t get killed over a new idea in any other major religion!!.
