It absolutely will, though.
The Kardashians are the most famous family in the world. Every American knows of, keeps up with, and/or cares about the entire family - or at the very least one of the family members. The Kardashian Kraze extends to all age groups, genders, ethnicity, political views, etc. The reach is insane.
Bruce coming out as Caitlyn exposes every American to the, or at least, a, reality of being transgender. It forces pretty much every American to confront this reality. It starts a very real conversation. Conservative individuals who may have happily wished to believe that being transgender is something foreign, freakish, extreme and flamboyant now have a very real example of a relatable individual (a middle aged, white, male, Republican, athletic, family-man) who is coming out, clearing the air, making a change and is now owning their true identity. That hits close to home. That changes perspectives. That opens minds. That kind of relatability makes people think differently.
So while it's certainly fair that many are apprehensive or distant to anything coming from the Kardashian family - I don't think it's fair to discredit the importance and potential impact this cover, and Bruce's transformation in general, will have. I certainly am no Kardashian fan - in fact I've never seen a single episode of the show - but I'm not opposed to the possibility of something genuinely positive coming out of the crazy.
