There are other groups that could claim the same: Romany/Gypsies would be a big one but no one seems to want to claim a North Indian homeland for them; Sikhs might be another.
I'm not sure what you're trying to say, but if there are other groups who are being discriminated against, and have a strong connection to a specific place on earth - be it Romany, Palestinians or whoever - I definitely wouldn't be the one objecting their right for self-determination. The way I studied Zionism as a child was clear: through our (Jews') right to a land we can understand the right to land of others.
