They're freaking out because they've been conditioned to freak out. For whatever reason, the Democrats elevated Ruth to the point of godhood, to a point that is clearly fucking unhealthy and only escaping the denotation of a cult by means of not actually giving it a name. If push ever comes to shove, though, and you isolate someone who praises Ginsberg's life as though she were the second coming of Christ, ask them to explain why.
Without looking at their phones, without consulting a Wikipedia entry, without forcing you to watch some dumb YouTube video from ya' boy Skinnypenis, ask them to explain specifically what she's done to earn this cult-like worship. What were her last three dissents and opinions? What were her landmark decisions? Why is it important that she be on the Supreme Court?
Every bleeding heart that I've ever met worshipped the ground that she walked on, but I've spent the past four years asking all of them why that was, and I never got an answer unless it was "Roe V Wade", but even then they couldn't tell me her opinion, only that she helped pass it. The sad reality of it is that Ruth Bader Ginsberg never meant anything to these people. Ruth wasn't important in the slightest, and her life never mattered to them, only her ability to stay alive.
Ginsberg was a Democrat on the Supreme Court and that's literally the only reason that they cared about her.
