There is no such thing as a "Palestinian". "Palestinians" didn't start calling themselves "Palestinians" until the early sixties.
It's true that Palestinians did not start calling themselves as such until the early 1960s and that in the 1940s if people were described as "Palestinians," that usually meant they were Jewish. However, that does not mean that there are no such people as Palestinians. National identities can be created very quickly and are just as valid as anyone else's - remember the story of Rip Van Winkle, a good subject of King George III, who wakes twenty years later to find the men of his village have become loyal Americans?
They're ancestors were planted there as a part of an old Islamic conspiracy to take over the world. After the Jews left the "Palestinians" came and started calling themselves "native" there (Despite what the liberal media say, the "Palestinians" are the land thieves, not the Jews).
As you're unable to spell "their," I'm not going to give what you say about politics, sociology or, as we shall see, geography, that much credence. As it is, the makeup of the Palestinian people is rather more complex than that, running from Islamized and Arabized people who had always lived there to economic migrants in the 1960s and everything in between.
Also don't give me that myth about how Jews and Muslims lived in peace until Israel was formed (and made the Levant a civilized country). The Jews were the "Palestinians'" dhimmis. That is not "living in peace".
Compared to what Christian Europe had to offer, it was living in peace. So much so, that there were Jewish communities with an unbroken presence since Biblical times and Jerusalem had a Jewish majority. And the Levant has never been a country; it's like calling the Balkans a country. The region has been civilized since antiquity.
The EU agreed to turn their back's on Israel and accept Muslim immigrants in exchange for oil.
Except that a) there is strong trade between Israel and the EU; and b) Muslim immigrants were coming to EU countries before either the EU or Israel existed. Furthermore, most come from those EU countries' traditional areas of interest, i.e. North, West, and East Africa, the Indian Subcontinent, South-East Asia, and Turkey. Very few are from the Levant and Muslims aren't the same wherever you are. And Europeans produce their own oil and buy from anyone willing to sell.
A lot of Europeans admire left-wing dictators like Stalin, Hitler(He was left-wing. Left-wing is big government and right-wing is small government) and Mao.
How many would you say? My guess for Stalin and Mao is (excluding Russia and the Caucasus) probably fewer than 50,000. In all Europe. With more than 500,000,000 people. And you can redefine words to mean what you want them to, but it still doesn't alter the fact that Hitler is right-wing in the classical definition of the term which everyone else uses.
A lot of Europeans are openly anti-semitic and beat up Jews and accept Islam.
The Europeans who accept Islam are called "Muslims." Anti-Semitism is, I'm sorry to say, a lot more acceptable in polite company than it was a few years ago. But it was a lot worse 60 years ago and it varies a great deal across the continent: I'd feel far more worried about being Jewish if I lived in, say, France, Hungary, or Sweden than here in Muslim Kosovo.
Liberalism will be the death of Europe.
Liberalism saved Europe twice in the last hundred years from autocracy and totalitarianism. The United States is founded on principles of liberalism. Think again.
It won't be long before Europe collapses under the Muslim hordes and becomes "Eurabia". In case you don't believe me read "While Europe Slept".
There are one or two well-made points in the book, but the thesis of Eurabia is built on exaggerations and intellectual dishonesty. And we know where it can lead; Anders Behring Breivik heartily approved of the Eurabia thesis.
