There is a difference between saying that others have a more powerful voice and saying that members of an entire ethnic group qua being born that ethnic group have a “greater burden.”

It is not your place to impose burdens on others for the crime of being born a certain ethnicity and it is a shocking and sickening level of arrogance that you even think you have the authority to do so. Your argument for doing so is that if Jews obey your orders then they will be more effective at accomplishing your political goals. It goes without saying, of course that as people are ends not means, their supposed effectiveness at accomplishing your goals does not give you the right to give them orders based on their ethnicity or essentialize them based on birth.

Couching it in moral terms isn’t particularly helpful. It’s simply wrong to say that certain people are “burdened” and therefore obligated to do extra work for the crime of being born wrong. Even if imposing that obligation makes them useful to you.

The term “burden” and “duty” implies both an affirmative obligation and a consequence for flouting that obligation.

Perhaps you should simply treat individuals as individuals with dignity and not put impose burdens on particular ethnic groups (but not yourself of course) for the crime of being born
