In that context, "of all people" makes sense to me. I too have been surprised by the move, of some on the right, against Israel, considering their almost unanimous support previously.
The right is not a monolith. Various elements on the right have always been anti-Israel, from the non-interventionists to the straight-up racists. Kirk was one of the former.
As the genocide has become more and more indefensible, many right wing water carriers (also including Tucker Carlson) have been peeling off and voicing occasional (but essentially harmless) criticisms of the relationship. It's more cynicism than principle.
And the more I've read into Kirk, the more disgusted I've been.
Obviously, that doesn't justify what happened to him, but he definitely isn't some kind of saviour and hero he's been made out to be after his death.
Watching him effectively being made into a saint has been mildly nauseating.

Edit: to be clear I read the study and they used Prolific (https://www.prolific.com/) to get the participants but that means nothing to me.

This and my original comment apparently struck a nerve for some people, but I’m just sharing what I observe from the links I’ve included. I’d love to see some actual response to the content of these videos given Kirk’s apparent change of heart on Israel (especially if I’m off-base) as opposed to just downvotes with substance-free responses
