I don’t know whether the posters you refer to are pro-Palestinian. To be honest, I don’t read the posts, I find them one-sided, repetitive and argumentative. Generally I do read yours though.
Regarding 7/10, and justifying or excusing, past deeds. I did neither, I simply said it helps understanding why what has happened has happened. I don’t excuse or justify it. I’m sure if the past was not as it was, we wouldn’t be in the situation of terrorists massacring Israelis and Israelis going in to find them with enormous collateral damage.
