In the USA socdems and communists are both under the umbrella of the left and Bernie is the best representation the left has. Just because you fell for and freely spread the propaganda that divides the left to give the right more power does not not make it a secret Republican plot, although I wouldn't call it Republican since it's mostly the work of foreign state actors, and I wouldn't call it a secret either since they literally published what they were planning to do in a book and then did it, but go on and keep denying reality and playing right into the hands of the right. You're really helping communism by driving that wedge even further!
