But it IS. We can argue about specifically what subsection we're talking about, how it's defined economically or geographically or politically, but it's still a subsection. I'm certainly not saying there's no such thing as "white culture," but that site's picked a very specific liberal guilt-ridden slice of it to generalize as the whole. And I belong to that subsection. My rural, conservative, all-white hometown does not - most people reading it from there would be laughing at "them," not "us."
