That said, my education strongly tells me that there is indeed something reflecting fascism coming alive and I don't look at Israel here.
The self reflection about innocents being harmed is something that you can see exclusively in Israel with very few exceptions. That is not an indignation of Palestinian children that have constantly exposed to severe propaganda, but at least have the decency to not blame Israel for that.
The parent comment also was wrong with his analysis of Israel being a result of western powers wanting some form of outpost. This is just bad history.
I don't think people outside Israel think that Israelis are engaged in self reflection. That aspect isn't something that's reported on. There are some Israelis that don't care about innocents in Gaza, and it's easy to just pick up that story if it furthers the reality that you believe in. Reality isn't one, or two, or one hundred stories. It is a continuum.
Israel being a "western colonial enterprise" is not an analysis. It is a talking point. I've seen it hundreds if not thousands of times in online discourse on this topic. It's something that has been pushed for some time (a decade or two?) in various circles. The history of Israel can be studied superficially in one semester in University. To really understand the period and all the nuances, and the related historical processes, get a PhD. There are good lectures on YouTube by historians and good resources on the Internet that give you a taste but you need to put in time.
It's also about the semantics, what exactly do these terms mean, a common theme in the information war arena is to use words in unusual ways or to redefine them in a way more convenient to your cause.
I'd say the connection of Israeli Jews to the land is stronger than the connection of most citizens of most countries to their land. To descibe that as "tenuous" is at best unfair.
[EDIT: erased a bit of not so nice retort]
Israel's right wing isn't very different than right wing parties in other parts of the western world. I'm not a fan of Israel's extreme right but conflating the violence between Israelis and Palestinians with either the rise of fascism or South Africa is just again yield to propaganda. The various governments of the Palestinians, the PA or the Hamas, make the Israeli right wing look centric. Put aside the various labels that are intended to dehumanize the Israelis, after Israel tried in earnest to make peace roughly around the proposed two state solution and was met by a wave of Hamas suicide bombers that impacted at some level every single Israeli, what do you think is an actual solution here?
