As @GhostOfMatchesMalone just said - stop what? Justice Thomas can go on vacation. Sotomayor can write books.But I said that you're correct and I am not defending her. They all need to stop it. You can't even admit that.
One of them heard cases involving a company that's paid them millions since 2009, and should have recused herself. How could she not be biased? If she ruled against her publisher and cost them financial harm do you think they'd still want to do business with her?
Now do Thomas, what opinions, cases or decisions were affected by his vacations?
