Part of the problem is that they're just tourists so they think the Republicans win every court case they get to scotus, which isn't true -- if SCOTUS was just an organ of the Republican party, Trump would be just about to finish his second term in office.

Most people criticizing don't realize for example that the court has had an overwhelming number of cases that ended up being 7-0 recently, and there's cases where some liberal justices and some conservative justices combined to get a slim outcome. They're not politicians, they're judges and have a different view of the world. Under Trump most Republicans hated Roberts for example.

Many such people think they would have opposed the Nazis if they were Germans in 1936, while loving who the establishment tells them to love and hating who the establishment tells them to hate and not realizing their behavior would have aligned them directly with the Nazis in Germany in 1936.
