Israel Are the Palestinian Arabs as they claim really victims, or are they victim-makers?

...how you will seek to disabuse such Jewish people of their misapprehension, while making certain to keep within the size of text you have let me know you consider appropriate; and also while providing them with proof for your reasoning, so they will be less likely to react to you by dismissing what you say to them, as: “Propaganda”, “Hasbara”, “D[/b]ehumanization”,[b] “Subterfuge”, “Rant”, “Lies”, “Fake”, “Spam”...

The best way to do so would be to expose them to the dangers of having such elements within a near proximity. Ultimately, the burden of proof is on those sceptics and not on us informed ones.

It is necessary however, to actively debunk "Palestinian" Arab falsehood propaganda, since otherwise young impressionable people, or older people who have not yet made up their minds on the dispute, tend to believe what they are told in the absence of rebuttal. 

You are correct about the burden of proof, which must be made clear, yet as part of rebuttal. 
One way I draw the reader's attention to the burden of proof, is as follows:
"The pro-"Palestinian" Arab contributor falsely-accuses Israel of [insert propaganda e.g.: genocide], while insulting the reader's intelligence, by providing for their falsehood: No detail(s), no objective-sources; zero evidence."
