1) What scholars? Because everything I see is garbage. Prime example--they compared two different lists of the dead in Gaza. A capture/recapture model to estimate what percent was actually captured. But capture/recapture inherently requires your captures to be independent and the second list was specifically an attempt to catch those missed by the first. Thus the two lists were not remotely independent.
2) Unfortunately, most sources are not willing to report things Hamas does not want reported--reporting things Hamas doesn't like would interfere with their ability to report anything. Thus you're stuck with mostly Israeli sources. But Israel has published lists. And, notably, nobody comes along and shows any problems with the Israeli reporting. It's always dismissed without evidence--and that is pretty strong indication that it's true. In discerning the truth between competing sides look at how each side responds to the claims of the other.
3) Once again, Israel has published lists. And note that you are presuming your conclusion in your argument. You can't claim Israel shoots innocents because Israel shoots innocents. And you also are presenting without evidence the claim that Israel was trying to starve Gaza.
I will not deny that Israel shoots "journalists"--because the propaganda people pretend they are journalists. And, likewise, "humanitarian" aid workers--the aid system was basically controlled by Hamas and used to maintain control over the population. It's the unfortunate reality of almost all "aid" operations--the aid is controlled by the very people who cause the situation and is used to maintain control. Gaza is normal, not an outlier.
4) Israel put out some stuff showing "dead" that weren't. Things like a group of "dead" where the identity numbers were sequential, the names were different, the rest of the details were the same. Really, now, a bunch of people with sequential ID numbers die together???? Especially when sequential ID numbers aren't possible with their system. (The ID numbers have a check digit.)
I am decidedly not fine with ethnic cleansing in Gaza, I just do not think it's going on. Hamas engineered an atrocity to make you think Israel is evil.
