Pappe is biased towards Palestinian emancipation. He explains his position and why in his introductions instead of hiding his bias like some Historians such as Benny Morris, who has justified the ethnic cleansing of Palestinians in 1948.
Here’s Pappe’s response to Benny Morris, where he debunks Morris’ claims:

CAMERA criticisms are easily debunked as seen here:

“Ben-Gurion’s 5 October 1937 letter thoroughly vindicates Ilan Pappé’s reading; indeed, the Pappé quotes to which CAMERA objects seem almost mild when compared to the actual words Ben-Gurion penned to his son. The more literal translation of the Ben-Gurion direct quote (“Webmust expel Arabs and take their place”) is actually stronger than Pappé’s freer rendering (“The Arabs must go”), although the meaning is basically the same. As for Pappé’s paraphrase, it is as accurate and comprehensive as any so succinct a sentence could possibly be.”
There’s plenty of reputable historians praising Pappe’s work and credibility. The criticisms don’t hold water. Maybe don’t be so quick to discredit his works. His works use a wide variety of sources.
Electrinic intifada:
From Wikipedia:
There is consensus that The Electronic Intifada is generally unreliable with respect to its reputation for accuracy, fact-checking, and error-correction. Almost all editors consider The Electronic Intifada a biased and opinionated source, so their statements should be attributed.
Mondoweis:
“Mondoweiss” is a hate site (UPDATED) from the Washington Post.
There is consensus that Media Bias/Fact Check is generally unreliable, as it is self-published. Editors have questioned the methodology of the site’s ratings.

Even if you want to discredit those websites as a whole, it doesn’t change that those articles themselves are factual.
Mondoweiss is not a hate site. Anti-zionism is not Antisemitism.
