Well, then, I repeat, you're saying “this definition”. Someone tried to define it, and that's where you're getting into the problem. Stop trying to define what it is, because then you get into a debate in which all of a sudden some people can say it's nothing.
If anyone who is a Muslim finds that an action is against them as a Muslim, that should define or at least characterize what it is. Islamophobia means anything that will hurt, denigrate, etc., just as any other group would see it if it was a different group.
