Palestinian right of return

[Thunderbird is the word]

So I might be lighting a match with this post but here goes. If you believe that Israel should continue to exist in its current form, an ethnically Jewish defined state how do you square that with the fact that it violates the fundamental human right of return? Speaking as someone who is part Jewish I don't think it's right that I should be able to emigrate to Israel when my ancestors came from Russia and Poland but Palestinians who are only a generation or two removed shouldn't be able to. It's why I think that ideally there should be one secular state.
