That part is clear to me, but it seems not so much to many of the Palestinian supporters. I've never seen a muslim demonstration to ask Arab countries to take the Gaza population in and save them.
You want to end their suffering in the open air prison and you have 2 options. Fight against a military far superior enemy who is raining bombs on you or just take them people in, so they don't have to suffer Israelian bombs anymore. What is the easier and faster way to end the crisis and suffering for 2 million people?
That would require the love for Palestinians to be greater than the hatred of Israel of course and somehow, the majority doesn't see the hypocrisy in that. If you want to save civilians, there are better, faster and realistic ways. If you just hate Israel and don't want them to win, okay it's your right, but then don't hide behind the Palestinians suffering and admit the real reason.
It's not whataboutery, I answered to the question where would the 2 million people go (if their neighbours would actually be concered about them, and not just use them to ignite Israeli hatred.)
