Sheeeeeeeeeeeeeeeeeeeeeee-it.

Arguably it's been impartial ever since they first cleared the way for FDR's New Deal, told the farmers to EAGBOD. They then said it was okay to lock up Japanese Americans in internment camps and then they forced The Pledge of Allegiance into classrooms because fuck Jehovah's Witnesses and God Bless This War etc etc. This all happened in about ten years time ('33-'42) but somewhere in there you could say that a lot of people felt that the SCOTUS was anything but impartial. They finally allowed women to vote only in 1920 and black people couldn't realistically vote in a lot of places until into the 60's and only after a lot of bitching and crying by the sitting justices at the time and they didn't stop obvious racist gerrymandering until 1980 ffs.

Don't get me started about marijuana, the prison system and the Christian Right's long influence on the bench.

Impartial? That's a hoot.
