Actually the Pepsi ad invited so much derision and mockery from all sides- not just from the Liberals- and it centers on just how bad of an ad it is. It's unbelievable in fact that during the whole process from conception to execution, not one member of the creative team stopped for a moment and asked- is this really a good idea?
In fact, there's a really entertaining and insightful list of questions that came out regarding the ad worth reading:
http://www.slate.com/blogs/browbeat/2017/04/05/_30_questions_for_pepsi_s_protest_inspired_commercial_starring_kendall_jenner.htmlThe core problem is that the ad pushes the absolutely ludicrous idea that Pepsi is the solution to all the conflicts and protests that are currently happening out there. It's manipulative in an obvious, hammer-to-the face way- with no subtlety whatsoever. Just a perfect example of very bad advertising.
It's a commercial. It's not manipulative. Have people become so stupid they cannot separate reality from fiction?
