They only really make fun of communists "the most" in the sense that it's the difference between constant mostly friendly teasing and occasional genuine disdain, but at the end of the day Communism is the only ideology presented in the game as fostering hope for the future and having an actual plan to make things better, to an almost satirical extent given that you genuinely will a physically impossible miniature construct to stand upright for a brief moment.

Meanwhile Fascism is so pathetic that the most empathetic part of its portrayal is that it kind of functions more as self harm to Harry, with him apparently willing himself into facial paralysis and brain damage by the end of the Fascism quest, Ultraliberalisms representatives are rabid death squad mercenaries and the woman who partially hired them, who in this context becomes extremely menacing as a closeted bourgeois nationalist, and Moralism is the people who kill everyone who ever wanted something better for the world, to which Harry is so completely removed from that power that if he becomes a Moralist he just fucking spouts complete bureaucratic gibberish like hes citing scripture.
