terrorism
/ˈtɛrərɪzəm/Submit
noun
the unlawful use of violence and intimidation, especially against civilians, in the pursuit of political aims.

I would say that the horrific crime you are talking about comes into that definition. The perpetrator admitted he hated muslims and planned to do what he did thats where the pursuit of political aims fits in. If you were to deny that you would also have to deny any Muslim attacks as being terrorism...and you aint gonna do that are you?
