Also worth adding, since people don’t seem to realise this: The majority of Palestinians alive today were not of voting age when Hamas won those elections, and a very substantial proportion were not even born.
And even then, of course, while Hamas won the largest number of votes, even back then they still only had the support of a minority (ca. 44%) of the electorate.
Exit polls during the same election showed near 80% support for a peace agreement with Israel, and 75% who wanted Hamas policy towards Israel to change. In other words: It’s also disingenuous to see even the support for Hamas that was there in elections as support for the more extreme aspects of Hamas’ actions.
