You're conveniently ignoring the element of the pictures that truly raises the question of impartiality: THE CAPTIONS! You also ignore the blatant racist pictures of the black men with a bucket of chicken. Finally, you keep ignoring the importance of maintaining the public trust in his role as justice of the state supreme court, which makes me think you're completely naive or just trying to get a rise out of the board.
Alright then. You don't have to agree with this taste in jokes, and you certainly don't have to agree with his pictures. They are terrible things. If you want to argue that he's a shitty person based on these things I won't argue with you about that. Being a shitty person doesn't make you a shitty judge, though. If you want to argue that you should be held to a higher moral standard as a judge, I might concede that point to you, too. You probably should be held to a higher moral standard. I believe the term limit is 10 years on a PA Supreme Court judge. If he's an impartial judge despite his character, then what is the solution? Is having questionable character enough for him to be removed?
