Oh great, this brain dead moron is here with the offbrand hasbara talking points we've all heard before. Lets go through them
1) South Africa had a population that 75% non-white, Rhodesia had a 95% non-white population, Sri Lanka has a population that is 15% Tamil, Myanmar a population that is 6% - 10% Muslim. This doesn't change the fact that these were and are racial ethnostates because ethnostates can be diverse. What matters is the laws that pertain to these ethnicities. The Druze are Arabs btw and they still get their homes destroyed by the Israeli government, despite them being the "privilged minority" of the settler colony.
2) No matter how you justify it, because thats what this is, a flimsy justification, an ethnostate is an ethnostate. If the AfD called for a "Deutschstaat" or if Reform called for a state for "indigenous" ethnic Britons, we would recognise this as ethnonationalism and exclusionary dogwhistling. Could we get a quote from someone who used this version. A specific Palestinian leader mayhaps?
3) God, cool it with the cringe tumblr insults. "Asparagus spear?". "Yes we're just trying to keep to 1948 partition plan, please ignore all of the territorial expansions made since then, I promise you I will make some excuse about how Israel deserved that land because of right of conquest o algo. Please also ignore the occupation of the West Bank and the Golan Heights". Accepting the two state solutions offered by Israel is akin to Black South Africans accepting the Homelands/Bantustans as legitimate nations which only reactionaries, collaborators and traitors did.
4) So I read the article and in the thing you cited it shows that despite increasing desire to become Israeli citizens from the Palestinian population of Jerusalem between 2014 and 2017, out of 4,000 applications, 84 were approved, 161 were rejected and the rest were pending. So your evidence that "Oh no Palestinians can get citizenship" is that if you're a Palestinian, specifically from a part of Palestine that has been fully annexed and is administered by Israel, you can legally apply for citizenship but you're two times more likely to be rejected than accepted, if you even get a reply within 4 years?
In comparison, the Sri Lankan government granted citizenship to all Indian Tamils, a population that was brought to the country by the British, in 2004 and did so without any caveats. This was in the midst of a very bloody conflict with the Tamils in the north that culminated in a genocide at Mullivaikkal in 2009. You're telling me Israel can't do what a much poorer ethnostate could do during a far bloodier insurgency against the organisation that invented suicide bombing? (Big up the Tamil Tigers though)
Furthermore, as you kind of avoided, West Bankers and Gazans can not become citizens as shown by the Citizenship and Entry into Israel Law: “The law, passed July 31, 2003 prohibits Palestinian spouses from obtaining citizenship, permanent residency and temporary residency status in Israel by marriage to an Israeli citizen, a process referred to as “family reunification.” The provision also applies to children from the territories (West Bank and Gaza) who wish to live with an Israeli Arab parent”.
Any ethnostate facing an insurgency could use this claim of "We need to exclude people from citizenship because they share the same ethnicity as the group we are fighting against". It's not a refutation of discrimination, it's a justification for it.
Qatar is an evil country and if it or any of the fellow Kafala states is your base line you are doing pretty poorly to be quite honest. But I would ask, where did you get the idea you need for grandparents to be a citizen of Qatar? All information online points to needing only a Qatari father. Furthermore, it's not like Qatar gives citizenships away to all Arabs or even coethnics. There are stateless Bedouin groups in all the gulf states who are some of the primary victims of their states oppressive mechanisms.
5) So when you convert your DNA magically changes and transforms you into a Levantine? But a person from West Bank whose family have lived in the region for millenia and has far more "local ancestry" is an invader? The logic of the Zionist mind is most impressive.
I do love the "Protocols of the Elders of Doha" posting at the end, when Qatar is not a state based on ethnic supremacy as previously mentioned with the disenfranchisement of other Arabs, including those from what we would call "Qatar" today.
