This is how it worked for me: find a person that your leftist friend admires (e.g., Bill Maher) and state how he is now coming around on a lot of the stuff. Stuff that was freaking obvious to us years ago. BINGO Your friend will come around.
The point is that they won’t listen to you, but they’ll listen to Bill Maher.
Same thing with siblings. They won’t listen to you but to some cool dude.
It seems like a few freepers need to do that. My personal opinion. The ones who took the experimental shot know they are screwed, so have to joke around how they haven’t grown an extra arm, and try and discredit anyone who says the shots are bad.
