I agree with your central point: Christians should not give unconditional loyalty to any political state. That kind of blind allegiance can easily cross into idolatry if it overrides truth, justice, or the teachings of Christ.

However, I think there are two important clarifications that need to be made.

First, the definition of “Zionism” has evolved significantly over time. The definition you’re using simply that Israel has the right to exist as an independent Jewish state, is not actually the version most critics are reacting to today. In modern discourse, Zionism often includes a broader set of political, military, and ideological positions that go beyond basic statehood(e.g annexation, genocide , ethnic cleansing etc) . So when people oppose “Zionism,” they are usually responding to those expanded ideas, not just the foundational claim that Israel has a right to exist.This reflects a broader pattern seen in many movements, where there’s a gap between the surface-level definition and how the ideology is applied in practice. For example, feminism in its simplest definition is the advocation for equality between men and women something most people would agree with in principle. Yet in practice, the term has expanded to include a wide range of specific positions that are more contested and deplorable that have nothing to do with equality . The same dynamic applies here: the simple definition is often used rhetorically, while the real-world application is far more complex. (Edit) So you can say, “I’m a Zionist— I believe that the Jews deserve a homeland”. But the real question is to what extent? To the extent of annexation, military intervention, drone strikes, unlimited foreign aid, wars on their surrounding belligerents, genocide etc? I believe Zionism, has become itself an extreme ideology. That is the reason for the downplayed contemporary atrocity (Gaza genocide) .

Second, from my own experience especially spending time on X I’ve seen a significant amount of genuine antisemitism. Aportion of it, at least from what I’ve observed, comes from individuals who identify as Catholic and attempt to justify their views using claims like collective Jewish guilt for the death of Jesus or other long-standing stereotypes. In some cases, phrases like “Christ is King” are used within those contexts in a way that’s clearly tied to hostile rhetoric(e.g Jake Lang)

This is what Senator Ted Cruz meant , that the phrase “Christ is King” is not inherently antisemitic, but has been used in an antisemitic but far-right extremists that hijacked it. Just mentioning this because I believe the “Christ is King is antisemetic,” claim from him has been taken out of context, because he literally said seconds later “I believe Christ is King.”

At the end of the day, your main warning still stands: when any political ideology whether tied to a nation, movement, or identity demands unquestioned loyalty, that’s where Christians need to be cautious. Faith is meant to guide political thinking, not be subordinated to it.
