We like to think our society is in general getting a bit less racist. I think that's probably true, and that it's probably true that The Kids Today are a bit less racist than my generation was (when I was a kid explicitly racist jokes were really not taboo, though by the time I hit college they probably were). Still there's plenty of racism, and The Kids Today have plenty of racists, too. I'm not talking about the kids being idiots stuff, like halloween blackface*, I'm talking about real solid racism. I know where all the racism came from when I was a kid. It was, you know, normal. I'm not quite sure where they get it from today.
*I'm not saying that such things are merely stupid or suggesting they're harmless, just that some of it you can chalk up to stupidity more than antipathy.
