What does that have to do with what the main argument about them is?
To the extent the UN and international community have no say, and putting the theological arguments aside, the Palestinians can reasonably see the Jewish state as illegitimate and seek to destroy it. Their tactical use of violence to that end is not materially different than Israel did prior to 1948 and is common in war (allies carpet bombed axis civilian towns). I think international law explicitly allows an occupied party to target civilians, but anyways we would negating International laws.
In order to render Hamas strategy as unfair you have to either believe a religious right to Jewish presence (if not sovereignty), or expect them to accept the authority of the UN.
Which is why saying "Hamas doesn't represent the Palestinian people" (like Psaki did) is wrong. It is an attempt to absolve the average Palestinian from responsibility for the actions of Hamas who the majority of them elected (or would have if they had the chance).
So everybody who voted for Trump is complicit in everything he does and can't say he was just the lesser of two evils?
