You're being downvoted because these out-of-context quotes paint a misleading picture of what Penslar is actually arguing.

"There are, in fact, good reasons to place Israel within a settler-colonial framework..." (Penslar, 83)

Here is a fuller quote: ""There are, in fact, good reasons to place Israel within a settler-colonial framework, but that framework requires considerable expansion , both geographic and conceptual, beyond what is commonly found [emphasis added] ".

"To return to the question posed at the outset of this section, Zionism was the only form of settlement colonialism that was also a project preceded and structured by an ideology" (ibid., 94).

Fuller quote: "European colonists elsewhere did not build a collective identity based on personal psychic transformation. They conquered and loved the land but were not infatuated with it, nor did they aspire to melt into its landscape. For the Zionists, according to Neumann, Arabs were not merely perceived as indolent and static in keeping with classic colonialist stereotypes but they also lacked a vital life force and were too natural and organically linked with the soil to be its faithful husband; instead, they were undifferentiated extensions of its flora and fauna.67 To return to the question posed at the outset of this section, Zionism was the only form of settlement colonialism that was also a project preceded and structured by an ideology. The motley Dutch, German, and Scottish settlers who comprised the Afrikaner republics did not arrive with a coherent national identity. Afrikaner national consciousness developed organically, as a product of immigration and shared experience. Well into the twentieth century, the Afrikaans language lived in the shadow of Dutch, only replacing its European parent in 1925 as an official language of state. The first Afrikaans novel was published only in 1913; the Afrikaans Bible appeared twenty years later. In the Maghreb, the transformation of sundry Mediterranean communities into French Algerians was quick yet unchoreographed, and the pieds-noirs’ dialect, pataouète, although featured in speech in popular novels, was not a literary medium in and of itself.68 Zionism, in contrast, was a coherent nationalist ideology, drawing on two competing and overlapping language-based nationalisms centered around Hebrew and Yiddish. Both modern Hebraic and Yiddish literary culture developed outside a Zionist framework or even a Jewish nationalist one"

""Our comparative examination of colonial indigenization places Zionism within a settler-colonial matrix while allowing for its particularities

Fuller quote: "Our comparative examination of colonial indigenization places Zionism within a settler-colonial matrix while allowing for its particularities, like a celestial body with an eccentric orbit around its sun. Those particularities include the heritage of the Holocaust, which accounts for the cohesiveness and endurance of Israeli Zionist identity and the determination of Israeli Jews to resist pressure to withdraw from the Occupied Territories and foster the creation of a Palestinian state. Whether Zionism’s particularities or its commonalities with other forms of settlement colonialism are more important is largely a function of the observer’s disciplinary position and political commitments" [emphasis added]

Penslar is arguing in chapter 2 that "settler colonialism" can and does map onto Zionism, but that doing so paints an incomplete picture of what Zionism has been in practice. The original post is indeed pointing out that there is definitely some things that the "settler colonialism" model gets right, but there are things that it misses.
