This shouldn't be a challenge. Either you are moral, or you are not. Yes, there is often a grey area in moral discussions. But in the examples you are about to see, there is no grey.
The pro-'Palestinian' Jew-hate industry builds its Israel-is-evil case on lies. Watch this video. See if you can figure out what I mean.
The video is 6:09 in length. It was posted on youtube on October 18, 2015.
In my opinion, if the 'Palestinian Cause' was both just and moral, there'd be no need for the kinds of lies and misrepresentations you have just seen. What do you think?
