Let me speak plainly: It is not antisemitic to demand justice for all Palestinians living in their ancestral lands
I do not understand what he was trying to say. In 1948, the European Jews got rid of 90% of the indigenous people of Palestine and those who today are called the -Israeli Arabs- are the 10% that remained and their descendants. Therefore, it appears to me that he was not referring to the 90% of the indigenous population of Palestine that now live scattered around the world as refugees.
Today DNA has confirmed that the European Jews are 100% European but they claimed the land of Palestine by saying that they were 100% Hebrew. This man can say this and that but he will never say that the European Jews entered Palestine using a fictitious claim and therefore they have no right to it.
