i feel us drifting way off topic here, but what the hell, as long as its interesting, right? ^^
actually, i do think that shielding yourself off willfully is kinda ignorant. isnt that the definition of "ignoring" - not wanting to know? as opposed to opening up to other cultures, then making an informed decision, to what degree you want to follow the ways youve been brought up with (which are the product of a ever-changing cultural evolution themselves)
while its true that internationalism dilutes the "local colours" to a degree, im not concerned that the local culture will ever get lost. i grew up in switzerland, where almost every village has its own dialect, so much so that sometimes people from different areas of switzerland have trouble communicating. decades ago, linguists predicted that all local dialects will die out soon. yet here we are, the dialects are as healthy and alive (and ever-growing, ever-changing) as ever, and every swiss person is proud of their particular dialect. if anything, the increased mobility and availability of information has made people more aware, more proud of their heritage.
im sure you could find counter examples, especially in cases where violence was involved, which i of course dont approve of. but new cultures are being born all the time, so i guess sometimes an aspect of culture has to "die", too.
as for my "not paticularly enlightened, typically western view", ive had the luck of growig up with two cultures, and i can stand behind a lot of ideals with western origins, such as the human rights, feminism, separation of powers, democracy, or that the state should be seperated from the church. (yeah, there is some bad, bad stuff too. i didnt say i stand behind every western value.) but my original argument was that diversity is a good thing, so how exactly do you counter that by telling me im "too western"?
