Homogeneous if and only if you consider "white or European" to be a clear cultural classifier. Personally, I think that there are massive cultural differences between the US, Canada, UK, Australia, and every country in Europe. As an Australian, I'm a global minority and it might shock you but don't identify with many US cultural groups who are the overwhelming majority online.
