I'm not sure how that relates to what I posted.
On the left having f*cked everything up and created the space for Trump/ Brexit and Le Pen etc - I don't see how it was the left. What we've had in 'the West' has been a socially liberal/ economically rightwing concensus for the past 15-20 years. New Labour, Obama, Bruton's Labour, the EU and all the 'left' parties in that, none of them are leftwing. I mean, look around. All are in the centre and perhaps degrees towards the left - in the sense that Thatcher was technically left in comparison to Pinochet. But leftwing? In Ireland we talk of the hard-left, or the loonie left, these are people in the space Labour was 20 years ago, before they did what they did, i.e. became (acknowledged being?) middle-classed and moved accordingly.
Immigration played a huge part in the reaction to it all and gave us Brexit and Trump. But I don't think the 'liberals' as described above, which I think is more accurate than saying the left, can acknowledge the reality. Which is that mass immigration was allowed not so we can feel better about helping the less well off in other countries but rather for economic reasons - cheap labour keeping wages down, and also to staff what the West's economies have become, i.e. predominantly service industries. The amount of people with third level education in Ireland/ UK etc has exploded but what we need are people to work the shittier jobs - do you know how many Brazilians for example arrive here each year, to 'study' but actually just work the jobs an Irish person did 20 years ago but wouldn't touch now? And that's where the tension is in the UK and the US. Low paid, less educated peolple voted for Brexit and Trump, not because less educated = dumb racist motherfucker but because less educated = in direct competition for jobs with immigrants.
The liberals refused to face this reality, instead calling anybody who objected a racist. Then soon, the real racists got involved and reaped the reward.
The irony is, and you should read some of Sander's stuff from the campaign if you haven't already, that he identified, as far as I can tell, the issues and the causes of what was disenfranchising those voters. We might have seen two 'outsiders' (relatively speaking) aiming for the same ground, with the same rationale, but from radically different directions.
But he was shafted by the DNC. Perhaps because he wasn't an insider going to play along with the consensus.
