I'll just say this: I've never heard anyone advocate for the creation of a homosexual state or a gypsy state on the basis of their mass extermination in the Holocaust.
1. Sexual orientation doesn't lend itself to ethnic nationalism.
2. Roma probably aren't so interested in coalescing in a single area, given the place of nomadic life in their historical identity.
So if the Romani people want a state for themselves in the heart of India, should they get it? The Jews got their state by forcefully taking lands from others, perhaps the Romani should do the same. Of course having the British in control would have been helpful like it was in Palestine. The Romani should have made their move before 1947. Alas, now it's too late.
