As I said I have actually worked a lot in environments with a diverse leftist spectrum.
And in my experience backstabbing usually goes both ways and is a result of the previous hate (and a lot of the time because personal non political issues) not the other way around.
And yes. The only wins I’ve seen is when there have been total cooperation. Division is always the prelude of defeat.
And be ensure that I would be saying exactly the same words to any tankie who talks about “purging any leftist” no matter what their ridiculous arguments are for such a premise. I’ve heard it all and it is often just as untrue.
Just a note, from one political activist to another: saying “this election is the most important election in history EVERY SINGLE TIME” just gets people exhausted, and make them develop a disbelief in your words. People could not have lived through several “the most importan election in history” in a row.
