[Impossible]

I'm curious how much the internet has helped bridge this gap today and whether this idea of diversity through government-backed forced integration policies are really relevant/useful anymore. It seems very difficult to grow up in a culturally homogeneous environment today, you'd basically have to be a Luddite to accomplish that.

In my opinion the internet makes it just as easy to be culturally homogeneous if you want to. There are many people that, due to interest or necessity will be exposed to a variety of cultures, but you can just as easily filter your internet usage so you engage mostly with people that are like you. It doesn't help that on the internet, in text discussions, you don't know what someone's background is without research due to anonymity. For example, by default I assume everyone on HN is an upper middle class or wealthy white male in his mid-20s to early 40s, unless otherwise stated in the context of the comments, even though I know this isn't true. This creates the problem of, instead of viewing internet communities as diverse collections of people, they are viewed as stereotypical hive minds, further enforcing discrimination and stereotyped views of large groups of people.
