Is there a man named Joe Biden? Yes. There is a physical body that has lived for 80-odd years and been in politics for several decades. That body currently serves as the symbol of the presidency.
But the "person" inside that body is gone. This is what dementia does. Ask anyone who has lived with a loved one suffering from these diseases. The tragedy is "losing your loved one" before they die. Joe Biden is gone.
Anyone with even a remotely sensitive social sense can see that the "mind" inside this body is struggling mightily to hold on to even the most basic contextual framework within which he is operating.
Many many quotes now of him saying - with some variation - "I'm not allowed to talk to you guys." When someone is not allowed to speak, that person is not in control. They are a stand-in for the people who "allow" them to speak or not. Giving him a set outside the White House makes perfect sense. Those running the "Joe Biden" body need absolute control over it's utterances for those times when the body gets out of control or off-script. The stage is there because it allows them this technical control in a way the real-world settings of the oval office or the White House lawn don't.
Jen Psaki exists. Pay attention to what she says. Hers is the voice of a person actually involved in creating this shitshow. Anthony Fauci the same.
There are many people wielding a lot of power right now; Joe Biden is not one of them. As such, "Fuck Joe Biden" has very little meaning. Fuck the junta ruling under this name, absolutely. But let's keep carefully-open eyes on what's really going on here.
