There is some weird, stupid ass internet-era thing where if you ever feel the right wing may be a more imminent or more dangerous threat than capitalist liberals, you are not a good enough leftist
Liberals are bad because they'd rather ally with fascists than leftists, which is why leftists must never ally with liberals even when they claim to be fighting fascism
In the 1920s and early 1930s when bourgeous governments implemented social aid & reforms like the New Deal they were denounced by Comintern followers as "social fascism". When Stalin made nice with Hitler they stopped b/c they no longer could insult fascists. Then Hitler eliminated the KPD.
