It's difficult even to comprehend somebody honestly saying something this stupid, but our assumptions make morons of us all. Here are some facts, with decent linkage. Muslims account for less than 2% of terrorist attacks in Europe, In the US, it's more like 6%. 42% are committed by Latino groups, 24% by "extreme left-wing actors", whatever that means. More Americans die by being crushed under refrigerators than due to attacks by Muslims. More Americans were killed by toddlers in 2013 than by Muslims, assuming none of those toddlers were Muslims.
Since 9/11, Muslim terrorists have killed 37 Americans. During that time, 190,000 Americans were murdered by other Americans. So you tell me - is it sane to freak out about Islam?
