No it's not some anti-Zionist who is making that claim, it's Israel's Absorption Minister Sofa Landver (ironically, from the far right racist Yisrael Beiteinu Party) in an interview with the Jerusalem Post -- not a newspaper that even the far right wing of the ZF (that is, its leadership) can claim is "Israel bashing".
Here's a taster of what she said:
"We are racist. Israel is a very racist society. I know what olim have gone through over the past 20 years. Our nation does not know how to receive new immigrants," Landver says in a wide-ranging interview ahead of next week's Ashdod Conference on Immigration and Absorption. The main topics to be discussed during the event will be "Racism in Israeli Society," "The Immigrant Youth Crisis" and "Absorption Economics - Government Policies Versus Implementation."
"Veteran Israelis say that if our parents or grandparents suffered, anyone who gets to the country now should suffer too. But why? Why do olim have to go through this? Our society needs to change," Landver says.
Now, if it's racist towards Jewish immigrants, just look at how its non-Jewish citizens are treated.
