Well, I don't like typical unitedstatians and their culture (or lack thereof). There. I said it.
You get the distilled version of it though memes and jokes (some of which is more or less correct).
We have lots of culture, actually. There's a lot of things that bind all 300 million of us together, but being from 50 states and having all sorts of physical barriers, climates, races, ethnicities, religious sects, traditions, et cetera...mix that in with a somewhat schizophrenic concept of appreciating the unique, the singular hero/demi-god, the rebel/lone-problem-solver,
yet the need to belong to some sort of group, identification with others, the desire for approval and validation.
Which kind of makes it impossible precisely nail down us one type of culture.
But every now and then, on those Sometimes, you have to lower your freak flag.
On the other hand, we do have lots of big-box stores, all-encompassing media outlets, ideals of willfully dualistic nature, that sell the same products and services from coast-to-coast; stripped of regional flavor, that which sells a canned identity (it has a serial number), foisting the concept of ideals that cannot be bought (convince the masses their life will be changed/validated), that everything must and should be collected (more is always better), and that your beliefs can never have contradictions (never support the other team, we lose revenue that way).
Fortunately, a wise head or even a moment of awareness and clarity cleans the latter thoughts away (use as directed).
