It’s like saying that border control with Mexico is apartheid because the main motivation is racism against Mexicans. There’s a grain of truth (racism exists), but it’s not really the reason we have border control, and even if it was it still wouldn’t be apartheid. To see why Israel ended up with the current system, we have to consider a bunch of possible alternatives (eg giving citizenship to all residents), each of which runs into legal and/or security problems.
