Cynical use of people for political purposes

Regarding the controversy over the conversions of people with Jewish roots, an interesting observation occurred to me over the years –
Everyone accuses the rabbis of not being willing to bend the definition of halakhah to who is a Jew, so that it fits the wishes of Yair Lapid, Ben-Gurion, Menachem Begin, etc., etc., according to which everyone who is an Israeli patriot is actually a Jew, and they actually ask the rabbis to be precise, even complete atheists or at least people who don’t really believe in the obligation to observe the commandments.
These things are, of course, accusations and empty talk. This very demand is ridiculous and I suppose there is no need to elaborate on why it is ridiculous.
But I have a final question in this context. The morality of secular Zionism at the beginning of its establishment for bringing non-Jewish people into the state. In order to serve as a political tool to strengthen secular identity in Israel, these people are called to leave their homeland by telling them that this is their land. That they will be welcomed here as brothers in every way. And that this is a kind of secular state for all intents and purposes, except that it also happens to belong to the Jewish nation. When they get here, they hear in civics and history classes that their Christian grandparents were scum. They tried to steal the Jews’ identity. That the Jewish culture and people are a moral glory while the other nations are degenerate and deformed. They hear that on the news they are called an existential threat. The emissaries of the New Reform Fund and Zehava Galon are out to convert the entire Jewish people to Christianity and cause spiritual destruction. I am exaggerating the picture a little on purpose. There is no criticism here of the very national, extremist, and world-viewed atmosphere in recent years in many parts of society. My opinion on it is quite neutral. I also tend to think that although it is childish, it is perhaps quite healthy considering the Holocaust and other events.
But isn’t this intellectual dishonesty and a real theft of people’s opinions? When state institutions try to encourage people to come here, they forget to inform them that, with all due respect, in my opinion, a great many of the people in the population are not rational at all?
And I have already encountered cases in my youth of boys from the aforementioned populations who later developed attitudes that bordered (and perhaps rightly so from their perspective) on soft anti-Semitism as a result of these experiences.
What do you think? Beyond all the danger of assimilation and causing people (both Gentiles and Jews) to violate Torah prohibitions by marrying each other. Isn’t the reason I mentioned a reason in itself to abolish the father and grandson clause, which God knows why it was even included in the first place?
And why is there no one shouting about this important point at all among the Israeli public?
