Even though I'm an anarchist, I'm not completely opposed to occasionally petitioning "my" elected officials, generally by way of asking them to refrain from passing, or to repeal, some idiotic authoritarian law.
Today, however, I got an email asking me to "help us get 100,000 strong calling on the Supreme Court to overturn DOMA" (the fraudulently named "Defense of Marriage Act").
I'd certainly like to see DOMA overturned or repealed (and the government that passed it overthrown!), but the Supreme Court's job is to apply law, not to make law. Their decision on whether or not to overturn DOMA should, in theory, be based entirely on whether or not DOMA is constitutional, and not at all on how much popular pressure might be brought to bear on them by one side or the other (to make it so is presumably one reason why Supreme Court justices are appointed for life, not elected and subjected to periodic re-election).
So while I agree wholeheartedly with the goal, no dice.
