@SuneAuken I think this is not only true, but vital to keep repeating.
It's far more constructive to take the position "our side has a lot of work to do" but the other side is an existential threat.
This posturing as above the fray, beyond the need to push your own camp to be better, fosters disengagement and apathy - which serves the fascists. Exactly as it did in the 1930s.
Had those on the left held together in Germany, history would have been very different.
