Biden is not the issue. He does not call the shots. Mocking him helps very little.
He is a front, a figurehead, a puppet, just the spokesperson for the globalist/socialist/SJW/Democrats*. He reads what they tell him to read, then is told to STFU.
Biden is harmless looking, seems to be a good guy at first glance to the huge low information Dem base.
*They put him in after focus groups told them Booker, Bernie, Harris, Warren, Buttigieg, Yang, et al were all too weird-radical-abnormal, so they forced them all to pull out and let harmless Joe win.
Now we see a nice very old white grandpa tearing our Republic apart one day at a time.
