No one on here, though I question why PM is so pedantic on these issues rather than others, but historically i have witnessed a lack of support from movements and people who should be natural allies of disabled and sick people.
an example, today there has been a Stand Up to Racism event, very very well attended, org by the SWP, several momentum members/chairs in attendance, vicars, union types, etc, awhile ago a small disabled action group organise a well publicised meeting on the Crisis In Social Care, there were ten people there, one CLP chair, one Gp member, and other DASP, the unions, churches, wider left, etc, who attended the above, were absent. There is a hierarchy of oppression in the UK, more so, than Europe etc. what do you think i (and the sick people there)will take away from the contrast.
