I tend to view cultural preservation as a subtle form of racism.  That may sound harsh, and I know it doesn't reflect the core beliefs of many who may disagree, but this is why I tend to avoid cultural associations and gatherings, despite my (east) Indian heritage.  Much to the disappointment of my parents I'm sure, I've always viewed such "celebrations" as a form of "us versus them".  Also, why should a culture be preserved?  Is it perfect?  Is change or transformation a bad thing?  In reality, no culture is static.  The world is always changing.  Ok, I'll stop now.
