The problem is that Europe is split up into dozens of countries with very somewhat different values and cultures, so whenever you say "In Europe X happens", then you can always invoke some version of your argument.
Europe is France, Netherlands, Albania, Moldova. All of these are very different in various statistics.
To some degree yes, but mainstream US is still far more culturally uniform from state to state than Europe's countries are. In Europe most of countries are nation-based and as such encapsulate also all the possible differences in ethnicities, languages, culture, religion and history to a much higher degree. Imagine each race/denomination/ethical group in US having their own independent state with their own laws and ways of life, and you get something like Europe.
But there is still a common language in the us.
And national TV-networks with lots of viewers in both those states.
Neither of those are true for Europe.
I would argue that it is fair to say that the US is more homogeneous than Europe, especially if you are talking about the entire Europe, and not just the EU.
