I don't know. I think there are still people who are rebelling along those lines, opposing the establishment, but it might not seem as "fresh" or exciting as it used to back in the day, we're used to it now, so no-one really cares. If you could imagine a way of rebelling today that you would "applaud" or think was fitting for the times, what would/could it be? There doesn't seem to be the mass-movement rebellions anymore (like the 60/70's hippie movement, for instance, which was largely a fashionable fad anyway), but maybe that's a good thing. We're getting used to being democratic, tolerant and "progressive", nothing shocks us anymore (unless it involves some weird sexual practise or excrements or killing babies, or what have you, but hardly worthy rebellious causes).
