It says at least twice in the first section of the article that I cook for the homeless on a Monday night. In fact, I spend most of Sunday evening doing veg preparation, peeling and cutting, then overnight slow cookers take the strain - and Monday night I serve that home cooked and hot meal to the homeless folks in the area of London I live in. You're making my point. Homeless folks don't care about white privilege, they live from week to week and don't get much of a chance to debate in semantic arguments about intersectional privilege. That's what poverty does to you.
The quickest way to end poverty. Vote centre left. The labour party haven't been in power for over a decade. Why not? Identity politics has split the core base of economic socialists (Unions) from the intellectual middle class (issue based arguments). They are now at odds and the surge of identity politics cost Labour the North. Sure.... they'll hold London councils - but they won't make any in roads anywhere else.You want to help poor people - then don't get caught up in identity politics and push the economic argument in its place. If we reduce some of the burden of living on some of our poorest members of society, we'd likely resolve many of the issues that psychologically underpin racism. Fear of the other, scarcity mindset etc.
And no, adults don't declare they won't listen or talk to people who disagree with them. That is the provision of a certain type of leftist thinking and idealogue. So convinced of their own position that everyone else is the villain. That projected villainy comes back to bite them at the ballot box. See Brexit vote for example of this in action.
