Summarizing:

• NZ considers "Palestinian" an ethnic group in its census.

• The Abu-Rayya family refers to Palestinian ethnicity in their study regarding personal identification as Israeli or Palestinian.

• A link to list of every article on forward.com that contains the tag, "Palestinian," (why did you post this?)

• A student article in Ann Arbor's student newspaper refers to Palestinians as, "an ethnic group."

• An article full of videos disproving Palestinians are descended from Philistines, in which several of the videos seem to totally contradict your position. Did you watch them?:

  • 2nd video: says that Jews were considered Palestinians until 1948, and contains this quote: "The group of people that call themselves, 'Palestinians,' are mostly Arabs that come from neighboring countries like Egypt, Syria, Jordan and more."
  • 3rd video: Claims that Palestinians did not exist as an identity until around 1900 when, "More people in the area were developing a sense of being not just ethnic Arabs, but Palestinians, a unique national identity." National, not ethnic.

• A paper that refers to Palestinians as an ethnic group in a paper about service organizations for middle east minorities

While I appreciate that you bothered to present sources, these seem to just be google hits for "Palestinian ethnicity" rather than articles specifically chosen from credible sources because they support your case. Did you read them?

I’m guessing you won’t consider those “better sources” than a page anyone with an agenda can edit. But I’ll keep going if you want.

If you want to keep going please provide sources that are making this specific claim with evidence and not just articles that mention the words ethnic and Palestinian together in an unrelated context.

It seems to me that Palestinian is better classified as a national, not ethnic, identity. They consider themselves Arabs and were referred to collectively as such until Mandatory Palestine ended.
