The worst enemy of the left has been, is, and always will be, the left. The infighting is insane.
Idk about that, I would argue that the people that killed or imprisoned leftists or plan to do so have been/are the worst enemy of leftists. Like in Germany the nazis kinda killed or exiled a whole generation of leftists of all stripes. I think that is way worse than infighting, arguments or splitting up.
And calling something negative “insane” has a kinda ableist tone. I think other words would be equally effective in making your point.
Its not a garbage take. They had the chance before and didnt, why would anyone trust them to do it this time?
