At this point, I've long since tempered any rage I used to feel for the WBC. They're nothing but real-life trolls, feeding off the negative reaction they desperately attempt to create.
There are two ways to beat them. One it to ignore them. But that way is boring, so no one does it. The other is to just laugh at them, which is effectively what this is. Good on you, Foo Fighters. Go continue fighting foos (but don't pity them).
So remember children, if you ever run into the WBC, don't get angry. Just laugh in their faces.
