Why do people say that islam is a terrible religion? - the reasoning is pretty strait forward.
Listed below are just the last few of the 25,039 terrorist attacks committed by Muslims since 9/11/01 (a rate of about five a day) is incomplete because not all such attacks are picked up by international news sources, even those resulting in multiple loss of life.
These are not incidents of ordinary crime involving nominal Muslims killing for money or vendetta. Included are only incidents of deadly violence that are reasonably determined to have been committed out of religious duty - as interpreted by the perpetrator.

@Hush - you are missing the point. 25,039 known terrorist attacks have been committed by Muslims since 9/11/01 - that is a lot of very nutty members of your faith.
