Yes it is truth. It is part of their culture, there are some countries that accept minorities such as Lebanese, but that it because Lebanese Maronites where once a majority in their own country, but the truth is that Arabs have cause damage and massacres throughout all the North Africa and the Mid-East, against: Copts, Berbers, Tuareqs, Jews, Assyrians, Chaldeans, Persians, Druze, Bahá'ìs, Kurds, Armenians, etc.
They don't accept it and they are always going to deny it (Like thumbing down any single comment that goes pro-Israel and thumbing up anyone who say no-sense but against Israel). Some hate on Israel a lot, because it is an "illegal occupation", then he says (to fit the context hipocritely), "Jews and Arabs lived peacefully", well the truth is that Jews could immigrate to Israel because it was part of the British Mandate (not Ottoman anymore, which was Islamist), but Arabs didn't like that and that is why they proposed the creation of Israel. (They where acting in the same way they did towards the other minorities).
In fact do you know that "Palestine" is another name given to the Holy Land of the Jews along with Judea, Zion, Israel, etc.? And it is so stupid they talk about occupation and Arab nationalism, when 50% of Israel's population are MIZRAHI, that means Arab Jews. The rest are ASHKENAZI coming from Eastern Europe.
They are complaining because Israel (as well as Spain) meant another loss for Islam and you know how much they fight for territory, look what is going nowadays in Syria and Lebanon.
I love my country of origin, that is Lebanon, but really, I was not raised to hate on Israelis, like Arabs are in their countries.
Arabs have actually no rights to claim the whole Palestinian territory, since there was no "Palestinian state" just till the creation of it by the Brits, of which Jews also made part. They have to stick with their given territories. If they want a war, they will lose those territories like they have been doing throughout all these 60 years.
Another stuff: Ramzi is Arab obviously biased the same as Dun Dun! They willl do the best to wash your brain. On the other hand I am a secular Colombian guy who loves democracy.
