African National Congress, Scottish National Party etc. Not movements based on hatred
This is quite debatable. The ANC are known for their opposition to apartheid, something which I feel it was quite justifiable to hate. And you could argue the same for the SNP and the 'Westmonster' government. In reality - although they'd deny - it the movement is partly drive by (an entirely understandable IMO) hatred of the Tories. At least that's certainly true of my Morningside-dwelling Mother-not-in-law.
The word for that would be patriot/patriotism.
African National Congress, Scottish National Party etc. Not movements based on hatred, but on a sense that your country/people would be better off as independent and sovereign. There are people on Greenland who would like their country to separate from Denmark, there are those who would like to be part of Denmark. The ones who want independence are no more likely to be driven by hatred than the 'remainers' are likely to be racists who look down on the Inuit.
