But that =/= “every fascist is and always has been enabled by liberals.”

They’re saying that it’s very common for liberals to side with a rising fascist over the left in a misguided attempt to maintain the status quo. They’d typically rather move to the right instead of giving any quarter to the left, because the left wants to upend the structures of oppression, while the right wants to bolster them—while scapegoating an out-group.

Look at what macron is doing in France right now. Moving to the right to build a coalition with them to go against the majority left coalition that won the election.
