Defeatism is reactionary, comrade. If we believe our struggles don't matter they will never be resolved. If we believe we cannot win we will never try. No matter how hopeless everything may seem we have to believe that we can win because we objectively can. We are the majority. We are the cogs that keep the machine running and we can grind it to a halt if we so choose. We can do this and if pushed far enough we will do this.
The rise of social democracy shouldn't be seen as defeat; the failures of social democrat will drive further radicalizing. It already has. I was a social democrat myself once, as were many other comrades. Even Americans have their breaking point and we're on a fast track to it because social democrats can't beat fascists. Tides are turning if it doesn't seem like it.
Ignore Third Worldists. Workers everywhere are oppressed and we all deserve liberation. No one deserves to die on the streets. No one deserves to starve. That is the enemy's language.
We're still in Gramsci's Time of Monsters, but time moves forward. Always. And so must we.
