Hamas routinely calls for killing all Israelis and Jews. It’s in their charter as well.

Hamas are Islamist fanatics first and foremost. They don’t give a shit about the lives or wellbeing of Palestinians. Holy war for Islamic domination is their goal. Destruction of Israel and expulsion of Jews is just the first step in their ideological goal.

Hamas had a whole conference about what they would do after their victory against Israel.

15. In dealing with the Jewish settlers on Palestinian land, there must be a distinction in attitude towards [the following]: a fighter who must be killed; a [Jew] who is fleeing and can be left alone or be prosecuted for his crimes in the judicial arena; and a peaceful individual who gives himself up and can be [either] integrated or given time to leave.

Except they also want to enslave the useful Jews for a while.

16. Educated Jews and experts in the areas of medicine, engineering, technology, and civilian and military industry should be retained [in Palestine] for some time and should not be allowed to leave and take with them the knowledge and experience that they acquired while living in our land and enjoying its bounty, while we paid the price for all this in humiliation, poverty, sickness, deprivation, killing and arrests.

Hamas has nothing to do with liberation. Palestinians will never be free under Hamas rule.

It becomes a problem when pro Palestinians are purely anti Israel. The destruction of Israel is routinely demanded, which would mean death and displacement for half the world’s Jews.

A truly pro Palestinian position would also be against the religious fanatics of Hamas and their disregard for the wellbeing of Palestinians.
