When parties are openly and proudly abandoning women, disabled women, traumatised women, women needing refuge and rape crisis centres, BAME women, multi faith and multi culture women, women who need accessible provision, women with learning difficulties, homosexual people, child safeguarding....?
Leftist politics considers these groups important, and believes in accessibility and inclusion, multi culturalism, plurality. An equal accessible society. Fairness. Social justice. However the Labour/Green/SNP etc parties have abandoned these groups because they are incompatible with meeting the wishes of men and their supporters in identity politics.
Those parties may still identify as being left, and in part it's this peculiar delusion that 'left' now means 'good person' and 'my gang' and nothing else. But the facts and reality don't line up. Image and a lot of clownfish burbling and saying the words does not, in reality, a leftist party make.
