This comment is filled with baked-in assumptions on your part without any evidence of you trying to understand the systems beforehand. Marx used the term "dictatorship of the proletariat" to contrast liberal democracy as the "dictatorship of the bourgeoisie." Proletarian democracy depends on the large firms and key industries at minimum being publicly owned, so that the working class controls the economy and what everything else relies on.

You can't "hide" being bourgeoisie, and there's no reason "genocide" is necessary. These are ridiculous notions. Infiltration by opportunists is something that exists, and is why you can get kicked out of any competent party for wrecker behavior or opportinism.
