Nobody was claiming Palestinians were saints- the actual point is that their liberation struggle is not based on hatred of Jews, but on the natural human wish to not be subjugated by anyone, and an equally justified resentment at being made the target of badly-misdirected anger at the trauma suffered by another historically oppressed community when Palestinians themselves bear no responsibility for that trauma and could have done nothing to prevent it.
Is it really inconceivable to this author that Palestinians don't deserve to have the entire global history of antisemitism- a history which was largely though not exclusively inflicted by light-skinned Christians- used as a justification for dispossessing them from lands they've lived on for at least fourteen centuries? That it's time to admit that Palestinians could not have prevented the Holocaust? that Hitler was never going to be satisfied with simply creating a Judenrein Europe through forced population transfer?
At least two things can be true at the same time.
And these two things are simultaneously true:
Christian Europe has treated Jews barbarically.
Christian North America(the U.S. and Canada) enabled this barbarism by closing its doors to Jewish refugees in their hour of most desperate need, and will need to spend the rest of their histories finding the way to truly atone and acknowledge that.
Palestinians are not in any way to blame for any of that, and the Holocaust, horrific and unforgivable as it was, never in any sense justified what has been done to them since the 1940s, and especially since the Six Day War, when they were put under what now seems to be perpetual military occupation by the IDF, when most of their lands have been stolen to expand the illegal West Bank settlements, when any possibility of Palestinian self-determination was seemingly destroyed, once and for all.
Some other way needs to be found.
The wounds of one community can never be healed by the wounding of another- especially when the newly-wounded did not inflict the original wound.
