We don't actually have a far right in the UK; in international terms the tories are much nearer the middle left in many ways.
It has been the decision of all the left identifying parties to abandon women's rights, accessibility for women with disabilities/BAME/minority faiths and culture/ homosexual women, women with learning difficulties, women's equality of provision and access to leisure and sports and health care, and child safeguarding when and as it clashes with the absolute freedom of males to express gender identities. And to say that women's exclusion, injury and rapes is a worthwhile price to pay for the freedoms of self expression for those males.
It is, as you say, a very interesting view of life for a party claiming to represent the left, and it is now more that those parties identify as left rather than demonstrate any interest in those groups and their interests, particularly when those groups' needs and barriers are not serving them usefully. In many ways the very classist, 'for us and our pals, and sod the proles, they don't matter and we don't care' beliefs they now express is much nearer to the nastier side of the right.
But if safeguarding, women's rights and equalities, religious tolerance, multi culturalism and basic common sense is now the province of the right? Ok. I stand behind the principles, not the tribe.
