He removed a bad-faith message that needlessly brought up political issues. Good for him. One of the reasons I avoid many of these communities is the hateful, bad-faith political posturing. (One of my 4 grandparents was born in Gaza City, and expelled in 1929 [1], so I believe I have a right to an opinion on this.)
You wonder if there would have been a problem if he had said simply, free of political prodding, "I plan to give the same talk again in Ramallah. Is anyone interested in attending?"

Edit: So Hacker News are downvoting an actual descendant of a Gazan refugee for having a polite opinion on this? That's insane.
