I don't but I would if there was anything worthwhile. During college the only activism available was stopping the building of the "apartheid wall" or rallying to raise the income of illegal immigrant janitors at the University.
Once my liberal Jewish sociology of law professor gave out class credit for attending a "legalize the illegals" protest, so as you can see there was a whole range of options available.
Unfortunately the place where I am moving to probably won't have any better prospects...
