The trope description leaves the option of a memetic virus open, so it seems they are using it within the definition of the trope. I say it stays, as long as it is made clear it isn't the wiki's opinion, but just the way it is used in the example we're documenting. I don't see that example as being particularly jingo-istic. We're merely relaying how it was used. We've neutrally stated it is used by some opponents, and a specific example of how it is used without taking an actual opinion on it (pro or against).

We're descriptive, not prescriptive.
