"and I'll bet you still have a lot more to say."

No, not really. I mentioned Kasparov and not Fischer because an article I read concerning protest over the arrest of the three gals mentioned that Kasparov had been arrested while protesting on behalf of Pussy Riot. As for Fischer, I think he was one of the great chess players of all time; however, Yugoslavia and the UN declaration in the early 1990s kinda threw the US into a situation when Fischer and Spassky ignored the admonition and played there. Fischer was a bad boy. (I found his political views abhorrent, but that's another set of issues.)

The politicization of sport seemed to start with the Black Power salutes from the winner's podium in the 1968 Olympics, thus showing that what we hold sacred is determined for us by other people, especially people working at the behest of the state.

The US-led boycott of the 1980 Olympics to protest, ironically as it has turned out, the Soviet invasion of Afghanistan--was a further continuance of the pissing match between the USSR and the USA. IMO, it was not philosophy or the "we're more righteous than you because we are democratic and free" stuff from Washington that ended the Soviet Union. The USSR simply got out-spent by their world rivals. So I do fail to see the cogency of Fischer to the Pussy Riot gals unless you mean that both Fischer and they paid for questioning the authority, both written and unwritten, of the state, whether that state be the USA or Russia.

I think the method of protest that Pussy Riot used was certainly unwise and ill-considered. That aside, their actions have certainly drawn world attention to Russia and some human rights issues that need attention. The protest will not in and of itself cause change in Russia, but word got out and the world knows. And it's quite peculiar, really, because while the gals and the chess master have gone against the state with protest over the five month detention without trial, the USA has signed away their citizens' rights to habeas corpus--but then that isn't spoken of in polite company.

So, as I said, everything I had to say got said when I signed the petition. The rest is merely commentary.
