I'd say there is of course a range of opinions and different narratives on both sides (from from actively seeking coexistence to humanitarian to pragmatic to nationalist to religious fundamentalist to having a deep personal hate for the other side).

Then you have all kinds of different groups, factions and third parties with their own allegiances and motivation.

However all of those pieces arrange themselves around a central conflict which does have exactly two sides in my opinion, which are the Israeli and Palestine people, respectively their claims to live on the land. You can see this rather easily by observing which groups view each other as mortal enemies and which merely as a nuisance.

There are - thankfully - lots of people trying to bridge the divide and not aligning themselves only with one side. This is where we all should be headed, but it doesn't change the fact that currently there are sides.
