This latest Islamo-fascist attack is distressing to libs for a number of reasons.
One, it was not in the U.S who according to many libs is the cause of all the evil in the world. Libs think France is a great socialist country. It's not really that socialist but they think it is.
Number two, this guy was obviously a Jihadi and not some mental defective although they're doing their best to make him out as another one of those "lone wolf" mentally ill types who go around slaughtering innocent people for no reason whatsoever. It's becoming more and more difficult for the left to brush these things off as not related to Islam.
And number three, he didn't use an evil gun to kill most of his victims, he used a truck. That contradicts the "gun is the source of all killings" narrative pushed by the left. What, are they now going to try and ban motor vehicles? Actually, many on the left would like to do just that for other reasons, but now they can't blame guns as exclusive sources of death.
