okay, well then the word is social-fascist. he absolutely does have contact with the dnc, which is why he is allowed to run in their party. the fact that some democrats kind of don't like their coworkers doesn't render them materially enemies. for the same reason that republicans run on moderate democrats being communists, moderate democrats run on social democrats being communists.
i don't think you were arguing against this but i do think it deserves special attention. the reason social democrats are social-fascists is that they materially support and uphold imperialism. lenin notes in chapter 6 of Imperialism that one of the chief drivers of imperialism is the need to provide stability at home. in order to do that, you need some mechanism to transfer superprofits to people who otherwise would be rioting in the streets. social democrats provide that mechanism. their job is to force the capitalists to take their medicine. and to bring it back to the above, "of course they meet in rooms"
