Well said, Ken (again!). I feel like those who focus on 'climate justice' would do well to consider these aspects of class in the debate over emissions reduction. It often seems to only look at 3rd world countries and take into account the imbalance of global wealth that resulted from European/western colonisation of their countries and the 'prior accumulation' that resulted from the rapid industrialisation of those same colonising nations. Thunberg touches on it fairly typically (and with some deftness, proving that she can in fact respond to tough questions) in the above Davos vid from around 30:00, shifting the questioner's framing from 'under-developed' countries to one of them being 'over-exploited' and then admitting her privileged position in one of the exploitative countries and saying it's not for her or any other westerner to decide the path the exploited take.
Of course, a full accounting should look at the exploited groups within western countries and attempt to remedy the historical (and ongoing) injustices they face from the same system, even though they benefit in some ways from others further down in the hierarchy, and from access to the fruits of industrialisation, as much of a two-edged sword as that has been... This, for me, is where Dore has a point with his 'try to convince those who disagree with you' bit, and where many environmentalists fail, especially when caught in the middle class liberal trappings you identify. Maybe the justice and equality angles would be the best to emphasise for reaching those people rather than the 'just stop oil' slogan (though that is still fundamentally what has to happen if we're to stop the planet frying).
Anyway, I'm pretty solidly middle class, so probably am missing a bunch and don't really know what I'm talking about, so feel free to educate me if I'm talking rubbish.
cheers, I
PS: I've posted this XR video before where founders Roger Hallam, Gail Bradbrook and others discuss the challenges of articulating and enacting a working class environmentalism. I'm not convinced they're quite as salt-of-the-earth as they make out, but the points raised seem valid:
