Yes, I agree. USA is such a big country with a variety of people. I am only talking about that the general consensus when it comes to such matters are very influenced by the strong religious groups in the US, and that it does influence the general way US companies censor. So I belive that you can discuss these matter s of cultural differences based on a generalized view.
It does not necessarily draw a just picture of the culture as such and definitely not its population, but you can discuss how rules and consensus is applied in a country.
