I have never seen a comprehensive list of examples of how Arabs have abused, mistreated and discriminated against their Palestinian brethren. Here is my attempt.
Please send me any other major examples I missed (anything affecting hundreds of people or more) so this can become a reference post.
All Arab countries except Jordan: Palestinians are not allowed to become citizens of Arab countries, in accordance with Arab League Decree 1547 for 1959, “in order to preserve the Palestinian entity and Palestinian identity.” Even in Jordan they can no longer become citizens. (There have been some exceptions: Palestinian Christians in Lebanon in the 1950s, Palestinians born from Egyptian mothers in 2011.)
Palestinians face severe travel restrictions throughout the Arab world. They do not receive passports and their travel documents are only accepted by a few countries.
Palestinians cannot vote or run for office in national elections.
Children born to Palestinians do not get citizenship in their host countries, violating Article 7 of the Convention on the Rights of the Child.
1967: Jordan refused to allow Gazans who came after the Six Day War to become Jordanian citizens. Today some 165,000 Palestinians in Jordan cannot become citizens and get no government services.
1970: 3500-5000 Palestinians killed and 20,000 Palestinians expelled, their camps demolished, in the Black September events.
1988: Jordan revoked citizenship for millions of West Bank Palestinians as they declared “independence.” As usual, this move was justified as being for their own good.
2010: Jordan continued to revoke citizenship for thousands more Palestinians
2012: Jordan passed an electoral law that effectively limits the number of Palestinian members of Parliament to less than 10%
2014: Palestinians who are citizens are still denied equal rights in the military, and on getting college scholarships and being admitted to some public universities, among other areas.
1948: Placed all Palestine refugees that reached Egypt into camps, forced men to go back to Palestine to fight.
1949: Expelled all Palestinian from Egyptian camps into Gaza. Very few Palestinian Arabs were left in Egypt.
1950: Egypt refused any UNRWA presence on its territory, relegating it to Gaza.
1949 – 1956: Any Palestinians in Egypt were barred from schooling and employment.
2013: Hundreds of Palestinian refugees from Syria placed into jail as they try to enter Egypt
2013-now: Egypt has effectively closed the Rafah border with Gaza, even limiting hospital patients from traveling, effectively imprisoning 1.7 million Gazans.
1950-58: Would only issue one-way travel documents for Palestinians to leave the country
1962: Palestinians classified as “foreigners”: 73 job categories banned for Palestinians until 2010; now there are “only” 50 jobs off limits They are still banned from working as physicians, journalists, pharmacists or lawyers. They are not permitted to build new houses or own property, or even to repair their homes Martial law imposed on refugee camps Limitations on schools for Palestinian “foreigners”
1975-78: At least 5000 Palestinians killed in Lebanese civil war
1985-88: Thousands killed in “War of the Camps”
2007: 31,000 Palestinians homeless because while Lebanese Army destroyed Nahr el Balad camp
2013: Some 50,000 refugees from Syria treated differently from other Syrian refugees; expensive temporary short-term visas effectively make them criminals
2013: Lebanon starts turning some Palestinian Syrian refugees away at the border
Kuwait: 1991: 400,000 Palestinians were harassed and forced out of the country.
