There needs to be rational pushback against the abuse of the term antisemitic. Its getting so tired.

The irony is simply pointing out an observable trend of ethno-centric nepotism among certain entities of power is labelled with the deflective term anti-semitic/racist. In light of the fact that one is simply raising a concern about ethno-centric nepotism itself being an implicitly racist practice.

And there's a bigger context. It's not that this practice is some racially ingrained, unique vice of "muh Jews". It's a noticeable characteristic among the select few in the upper echelons of society and seats of power, from various people groups especially throughout history, who trust their "own" more than outsiders. Its not so much some nefarious race-based vice, its a presumed insurance policy for hoarding and securing power with the assumption that higher loyalties can be maintained among those within one's same ethnic realm. Blood is thicker than water, etc. Especially when that ethnic group is a minority in the society in which members are holding power (a tenuous circumstance).

At the family / individual bloodline level, its pretty much the same reason European royals kept intermarrying to the point of biologic degeneracy.
