I wonder if Lenin ever ceased to attack Kerensky so the tsar could be overthrown? If he ceased his criticism of the Trudoviks? If he spoke out in support of progressive reformist of the Kadets? A socialist is not the attack dog of democrats, they are not a "proud boys"- type militia to be called upon and leashed again.

I think that is the concept that libs and socdems have of the modern far left (especially in the us)

'Attacking the preferable option is fundamentally counterproductive.'

'When will it not be?'

Incorrect.
