Hottinger glosses over the division forgetting to mention its origins literally with the death of Mohamed, himself. And his equating of American evangelicals with fundamentalists in Pakistan is academic bigotry, or pompous bigotry.
There are better sources for those interested in the origins of the divisions among Muslims, and the differences between Persians and Arabs.
the best option that I have discussed with others is to induce Iranis to convert en-masse to Zoroastrianism (or rather to RETURN to Zoroastrianism). In recent reports the numbers of Zoroastrians has soared to 2 million from 50,000 and there may be millions of hidden, secret Zoroastrians in Iran as many Iranis are truly fed up with Islam which they see as an Arab conspiracy to put down Persia (which if you go to the origins of Islam may very well be true)
“There are better sources for those interested in the origins of the divisions...”
At the end of the article’s continuation, a commenter lists several mistakes make by Mr. Hottinger. An interesting tidbit not listed here is that Assad the head of Syria belongs to the Shia offshot sect called Alawi. Only 6% of Syrians are Alawites. Even worse than the 30:70 split in Bahrein.
