Jesus told us that we can judge people by their fruits.
Take a look at the Muslim world, and discern what fruits Islam has brought forth:
War, terrorism, hate, slavery, persecution, repression, brutality, misogyny, etc.
On the positive side, I will admit that there were a few impressive cultural achievements at a few urban locations for a few years during the Islamic "golden age" almost a millennium ago. Examples: the Taj Mahal; the 1001 Nights. But these seem to be rather few and inferior compared to what has been ceated by most other great civilizations.
I will also admit that Islam is a relatively clean, non-idolatrous religion, and with the exception of its attitudes and relations toward females and infidels, emphasizes some commendable ethical principles. Again, though, there is nothing particularly unique about this.
I am left to conclude: there is much about Islam that is true and good, and much about Islam that is unique; however, nothing that is true and good in Islam is unique, and everything in Islam that is unique is neither true nor good.
