While I agree, Limbaugh was just a radio host. A very popular one, but he was still a private citizen who didn't hold any power. RBG was a senator who had been knocking on death's door for longer than most of us have even been alive, and there was a whole shitload of overly dramatic performative crying on social media, as if they had lost their dearest family member, only to snap straight back into your usual every day throwing of temper tantrums over the most minute happenings.
So when RBG died, we got to see a shitload of horrible people acting like their despair had hit rock bottom, and along with some of the dodgy shit she supported, like lowering the age of consent to 12 (making specifically just BoxerShorts47 happy), it was hard not to dance on her grave.
Rush Limbaugh is a conservative radio host who ranted on his show that you could completely ignore by just not tuning in. I don't think I've ever heard more than like ten minutes total of his show, and I hear more about what Ben Garrison's up to by way of his comics being memes than anything about Rush. I really don't know anything about him. Looks like he shouldn't have smoked so much, and he should have lost weight.
