And it was all cheered on by those who believed themselves to be on the right side of the establishment at that time. It was a regular thing to see and hear people fantasizing about the idea of forced injections, online and in real life.
And we learned about all this on, yes, social media (which was heavily censored at the time too).
The legacy media outlets were not telling the truth.
All this was only three years ago.
Things are a little different now, I'm sure you will find in many cases that forgiveness is possible in light of true apologies, but there will not be a forgetting.
And these things need to be honestly discussed if we are ever to achieve anything resembling national cohesion again.
