This feels thorny to weigh into, so let my preface it by saying that I am convinced that the cause of the widespread starvation is Israel's blockade. I do not believe there is some mass decision being made by Palestinians to starve their children, and all available evidence points towards Israel's actions as the cause. Some of the comments seen on other threads have been appalling.
The stakes are also so high that, even if someone were to lean towards thinking it is some twisted Hamas propaganda, the moral thing to do is end the blockade - the cost of being wrong is too high.
But, in their recent post at least (I dont track who says what on each thread), Lolapusht didnt seem to be talking about the current starvation in particular, but about martyrdom more generally. Obviously the response to her post has been strong condemnation, but I fear there's a material disconnect.
Belief in martyrdom is very prevalent in Palestinian society. Several books have been written on the topic, but I'll leave a wiki link (there is a notation on the link that the neutrality of the article is disputed, so do bear that in mind:
en.m.wikipedia.org/wiki/Martyrdom_in_Palestinian_society ).
Over the last quarter century, most polls by the Palestinian Center for Policy and Survey Research and Pew Research Center have, for example, shown around 70% support for suicide bombings (though one from the late 2010s showed a drop to barely-above one third).
There is no available data as to what % of parents in Palestine would be proud if their own child was a martyr, but there are academic studies on the coexistence of pride and grief in Palestinian parents so bereaved, so I don't think its some abstract or fringe issue.
Most societies have, at least at times, seen sacrifice for the greater good as extremely admirable. This is more prevelant in highly religious societies, and particularly in Islam (where the concept is particularly prominent in theology). Naturally, its also far more prevalent during times of war and occupation.
I - of course - don't think that Palestinians are inherently more likely to support martyrdom by their own children, but that its largely a product of faith and circumstances. If you grew up there, you'd probably be radicalized too, and most (if not all) Palestinians were born into hardship and a legacy of trauma.
(And yes, Jewish Israelis have their own legacy and experiences of trauma).
Dehumanization is a huge (and bilateral) issue in this conflict but its also one of the things that worries me most about what is unfolding, and the motives of Netanyahu and those in his orbit (as some have voiced.) If the current conflict stopped tomorrow, Palestinians would (understandly) be more radicalized than ever, such has been the extreme severity of Israel's response. That Israel persists nonetheless could be due to wanting the safe return of the hostages, but you have to worry that those making the decisions are counting on Palestinian radicalization not being a problem because there may be no more Palestinians in Gaza.
