Whoo is really an activist?

What I always find amusing from the right is whenever a court or judge rules on an issue they disagree with they call those judges "activist judges". Always. As the latest example I present the Iowa Supreme Court which recently allowed same-sex couples to marry. I say bravo to them. But I wonder when judges who actually are activist in their rulings (aka our SURPREME COURT in the ruling of Bush vs. Gore) why there is no outcry? Just the usual hypocritical G.O.P.O.C (for those who need a reminder that stands for grand old party of cowards which is what they are) selves.
