You didn't actually name a material goal or outcome. What was Lenin's goal then? What was the world he lived in and what message was he trying to send? Do you think Lenin would spend his time attacking a socdems that wanted to stop genocide while ignoring their further right opponent?

You literally didn't answer the question and just tried to appeal to some vague idea of "socdems bad". You're using Lenin like some religious figure. Like, this is not different than "Jesus said to pay taxes to Cesar" and then universally accepting that taxes should always be paid for all time and all places. You're apparently able to read the words of Lenin. But, not actually able to apply them if all you got from reading is "socdems always bad".

Also, to be worried about socdems you actually have to live in a world where socdems and communist are actually both viable political movements with organized power. You have to actually have a viable alternative. If you have no viable alternative then your actions of critizing socdems is only beneficial to the next viable alternative. The next viable alternative is fascism and support for Israel.

I WISH we lived in a world where I had to worry about the socdems siding with the fascist and betraying the revolution. But, holy shit mate, you don't live in Russia in the 1910s.
