The Quran is violent, Mohammed was violent, and Muslims in generel were violent for the past 1400 years.

Yes there are some Muslims that deny it. There are also people who deny the holocaust ever happened - But those don't get cheered on as "tolerant nazis", no, they are called conspiracy theorists or neonazis.

Muslims who deny that Islam is the most hateful and deadly ideology in the world are conspiracy theorists and are no better than people denying the holocaust.
