Nope. The Nordic countries are still controlled by capitalists, they (akd most of western Europe as well) just have given the workers some welfare policies in order to appease them and stop any revolutionary ideas. It's no coincidence that these policies were in place while the Eastern bloc was around and they began to dismantle the welfare state as soon as the USSR fell and they felt they could get away with it.
(Disclaimer: I'm not saying that the welfare state is evil, and that we'd be better with the shitty US way of doing things)
It's whitewashing because it's implying that genocide, leftist suppression, etc are the exclusive characteristics of a fascistic system instead of business as usual under capitalism. This removes the bad aspects of capitalism ("if this is happening it's because the US has turned fash, it's not capitalism's fault").
Fascism is the takeover of the state by the capitalists.
What. Capitalism is already the takeover of the state by capitalists. The state apparatus is just the means by which the dominant class exerts its power.
How is this whataboutism? They only pointed out that the US has a long history of doing shitty things without being controlled by some foreign actor. It's perfectly plausible that Trump is doing shitty things because he thinks he will personally gain something out of it, without anyone pulling his strings. He just doesn't care if the rest of the country goes up in flames.
True
