According to their statement, they have long banned for "hateful treatment of people based on characteristics such as race, ethnicity or religion", and white supremacy has long fallen under that. They also say that nationalism does not usually fall under this, with things like "American pride" or "Basque separatism" being an important part of people's identities.
What they say is changing is that in the specific case of white nationalism and separatism the overlap with white supremacy is nearly total to the point that they cannot be meaningfully separated.
This comment confuses me unless the claim is that Hinduism forms a nation within India, and the existence of such a nation justifies the violence committed in its name.
