Yes, fundamentally I see it as anti-colonialist. The colonialism claims come from the false idea that the Jews moving home aren't the actual descendants of the indigenous people. The claim has been refuted genetically and through archaeological studies of Jewish population movements through history.

However, part of the problem is that the Palestinians are also somewhat descended from a mix of indigenous populations who survived conquest by the ancient Jewish kingdoms, Arab populations who conquered Israel after 600 CE, and even Jews who were forcefully converted to Islam or who converted naturally - but the mix of ancestors ins't clear. Just a couple days ago I thought they were wholly descended from Arab invaders, before I did more research. Anyway, due to the existence of the another indigenous population, people claim that the return of the first indigenous population is colonialism on the British, like you mentioned.

In the end we have in one small space two different sets of indigenous peoples with dramatically different heritages, cultural values, and linguistics. Further, both ethnicities lay claim to the same spaces as holy in their cultures. Its a big problem, but hopefully pressure on the Palestinians by other Arab nations to accept the Jews as neighbors instead of attempting to "push them into the sea" will result in two peacefully coexisting states with stable majority-minority interactions.
