Bullshit. I will ask you the same question,
Why does that "make it worse"? And seriously, where is the documentation concerning the claim that "most" were immigrants or first generation Americans? What the hell, did the protestors enter through a gate producing their family tree? Oh wait, I know, Lisa saw pictures of them, and she can tell how long their family has been in the US by their LOOKS. Nothing racist about that, right?
This shit is beyond sick. For the uptenth time, what Hamas dis was terrible, it was a war crime. But they didn't do it because the people were Jews, they did because of years of mistreatment, years of Settlers stealing their land, burning their crops, harassing them, and yes, killing them. They did it because of the fact that Israel is an apartheid government, and if there was any doubt, that was removed when the Israeli government proclaimed that only the Jews have the right to self-determination.
The whole "anti-semite" charge is nothing more than a skirt that Israel and their supporters hide behind. Lisa is one of the biggest cowards that hides behind that skirt. Any criticism of Israel is automatically proclaimed as antisemitism. While ignoring the real illegal and immoral actions that the Israeli government commits. Mention that the Jewish settlements are illegal, that their residents routinely harass, and often kill, Palestinians in the West Bank with the tacit support of the IDF. "Antisemitism" they scream. They yield it like a get out of jail free card in a game of Monopoly, the only difference, they have an infinite supply.
