'How much do I blame Islam?'
Such a ridiculous, ignorant question!
Its the infidels fault, coz the infidels resolutely refuse to convert and to become moslems,
and,
its the infidels fault because they keep asking impertinent questions about our religion, when they should know by now that our religion is perfect and fixed, so all those impertinent questions are absolutely not allowed,
....never ever.

"
Fight those who believe not in Allah nor the Last Day, nor hold that forbidden which hath been forbidden by Allah and His Messenger, nor acknowledge the religion of Truth, (even if they are) of the People of the Book, until they pay the Jizya with willing submission, and feel themselves subdued. "
Koran 9.29
"O ye who believe!
Ask not questions about things which, if made plain to you, may cause you trouble.....
Some people before you did ask such questions, and on that account lost their faith."
Koran 5.101, 102
"We sent not a messenger, but to be obeyed..........they ['believers'] can have no (real) Faith, until they make thee judge in all disputes between them, and find in their souls no resistance against Thy decisions, but accept them with the fullest conviction."
Koran 4.64, 65
"O ye who believe! Obey Allah, and obey the messenger [i.e. the clerics], and make not vain your deeds!"
Koran 47:33
