Liberals in the Democratic party have spent the last several decades "working with the right" to "get things done". The only methods they know are to praise their bipartisan compromise.
They are just continuing what they have always been. A controlled opposition party that points to problems but never does anything to solve them. They were once the one step forward to the conservatives two steps back. But over the last decade that has changed. The conservatives stopped letting steps be taken forward and stopped playing the game they both benefited from.
So Fascism is here and all the liberals can do is point at things. Their role now is to normalize each step backwards. To be the party saying "hey, that's not legal!" or "hey, this is bad". It gives the greater population the feeling of normalcy as this has always been their role.
It makes the fascism feel like it's just "another 4 years" and something to be waited out. The liberals are filling their own role to bring about fascism. And that role is in a passive opposition pretending that the existing systems are still something that can be restored. The very systems that brought about the rise of fascist in the first place.
