Ever since Islam was invented by Mohammed, it has spread via the sword and forced conversions. The only reason there are millions and millions of Muslims today (other than the recent artifact of prison coversions and Saudi financed conversion factories in the US and some western countries) is:
1. Forced conversions
2. The descendents of forced converts cannot change religions.
Islam is more or less a prison. You cannot leave.
That’s it in a nutshell. If you read history (real history) you will see that the entire history of Islam is one of butchery, rape, torture, genocide, thuggery, theft and forced conversions.
That is all it is. They destroy other cultures, civilizations, populations, houses of worship, and the like.
It is butchery, plain and simple.
So what real history do you recommend? I’ve studied a good deal of history, but none of it ever described Islam in that way.
