We have to take all the wall down, not just parts of it.
I was particularly pleased to see pattrice jones explain how interlinked oppressions intertwine and multiply, rather than just add up (see the slide I used in a foundational sociology class for several years at the University of Wales, Bangor - top left).
For those following the new reducetarian fad in the animal advocacy movement, jones notes that we need to appreciate that the "mainstream" is not the majority, the majority is the collection of communities outside of the mainstream, alienated by "mainstreamness."
By uncritically pandering to the "mainstream," or what feminist-inspired sociologists have called the "malestream," - which is quite probably the most sexist, racist, and class privileged sectors in society - we push away and alienate the most radicalised and politicised elements of society.
