There are two primary objectives of such terrorist attacks. The first is to make people afraid.
The second is to drive a wedge between ordinary, peaceful Muslims and other groups in the hope that it will increase recruits for ISIS.
Clearly they have succeeded in both, judging from the comments in similar articles. 
Personally, I'll continue to judge people of any or no religion based on their character and behavior, not their stated religion since  I don't want the terrorists to win.

Those promoting the ISIS agenda of division and fear might want to rethink their position.
