It's not really dialog heavy, and 80% of the memes (at least the ones originating on the Internet) are there in the form of posters in one town.
I'm usually sensitive to such things, but I found the Mexican twist on all of these memes, and trying to guess which is which, was sort of entertaining. It would have offended me more if the game was severely lacking, and used them as a sloppy crutch, but it's not; they're just there for amusement, and they're easily avoidable.
