Oddly enough, despite the fact that the Dutch political climate is more left and quite different from the US, I'd say that many 'progressives' here
also hate 'traditionally their' parties (usually Labor and Greens and the like).
The term 'regressive left' is becoming more common in my surroundings, and ever since Pim Fortuyn (2002, the precursor to our Dutch version of Trump, and I don't mean that in a pejorative sense) there's been a growing sense that our 'left' not only lacks an answer to populism, it's part of the 'evil neoliberal establishment 1% elite etc.'.
There's a sentiment around me that Labor/greens/D66 (center-left democrats?) are mostly an intellectual elite that doesn't understand the problems we face. They call for integration and multiculturalism, but don't feel any of the adverse effects or problems that result. And somehow they seem way too much into privatizing things, dismantling our welfare state, and general Neoliberal-tasting things.
Now, I don't know enough to have a very strong opinion on all of this. But I do sort of get the intense hatred of the 'intellectual left elite'. It feels degrading and shitty to be told that you're wrong and your problems are bullshit and you're being manipulated by a populist, and you're a racist, and all that, and I can totally see how that could make one respond with a big middle finger and a vote for exactly those populists. Even if just out of spite. And even regardless of the consequences.
Of course I have no answer to this problem. I'm a well-educated, left-leaning, academically-minded, LGBT-affiliated white man and I'll probably do fine no matter what. I feel the way forward for me is to start engaging more with those who feel like they need to 'fuck shit up' with their vote, and to try and properly understand why all these things are happening that I didn't predict and that don't make sense to me.
But dear God I'm trying my best to bite my tongue and not blindly disparage Trump or our own populist movements. Because 1) it seems counter-productive, and 2) a surprising number of my highly-educated, intellectual-type friends are in favor of those movements, so I can't afford not taking them seriously.
And I suppose 3) most people are smarter than they seem, including the really dumb ones.
