Is American "movement liberalism" the most anti-"culture" ideology?

[I spent the winter writing songs about getting better]

Something that came to me in a discussion on AAD. But most American "movement liberals" do not give a f[inks] if any practice or element of one's identity is heavily tied to their culture or heritage if it has any conflict with liberal values. Anything that contradicts liberalism in any way must be destroyed. Notice how they don't care in the slightest about Columbus Day's importance to the Italian-American community, it must be abolished for not representing liberal values. They oppose any attempts to block Mexicans and Muslims from immigrating but once they do they want them to be completely assimilated.

Also as I noted, the strongholds of American "movement liberalism" tend to be extremely assimilated whitebread, generic white culture places. San Francisco, Seattle, Portland, Denver, Twin Cities, Madison, Austin are all notable for not having any real "white ethnic" neighborhoods, almost all the whites there are very assimilated whitebread types. Meanwhile it's worth noting that ethnic enclaves in major cities often do in fact vote Republican. For example Mt. Greenwood in Chicago is one of the few Republican parts of the city, all the Italians in Staten Island and parts of Brooklyn, Northeast Philly, South Boston (not as Republican in presidential elections generally, but if there's a swing toward Republicans it's one of the first places to flip.) Meanwhile the white liberal parts of those cities are all very assimilated and "non-ethnic", just like the whites in the cities mentioned previously.

Think of a stereotypical Bernie Sanders supporter. Does that seem like someone who'd frequently celebrate their ethnic traditions and heritage?

San Francisco is generic white culture? It's 42% non Hispanic white, and has the Mission, which has a long Hispanic tradition dating back to Spanish times, the Castro which is noted for its gay community, and the oldest Chinatown in the US. Go home, you're drunk.

1-I'm only talking about the whites in San Francisco.
2-San Francisco doesn't today (I suppose it did in Dan White's time) have any real "ethnic" white neighborhoods. The white areas are all very integrated and full of whites from all sorts of ethnic backgrounds. The Castro is actually a perfect example of this since it's a gay neighborhood, not one with any type of ethnic flavor.

Define "movement liberalism".

People on DU and DailyKos. 2004 Howard Dean supporters. 2006 anti-war netroots types who led the campaign to primary Joe Lieberman. White Obama supporters in 2008. Your average Bernie Sanders supporter.

I'm sure these people totally agree with you.
