What can be done with anything at all?
Look how Michael Moore edited Charlton Heston in "Bowling for Columbine" to completely change the tone of what Heston said at the convention, and how antis all ignored the hatchet job.
People will believe what they like. Not my concern. My concern is whether their belief is justifiable. In the case the OP suggested, it is, so we need to change that underlying truth.
In the case of zombie gear, we might just need to open a can of "Lighten up, Francis."
Otherwise, if we want to self-regulate away such things as levity, eccentricity, and individuality - we become just like the antis, don't we?
