You can't. Its like asking how you can refer to a state that has a strong racial and ethnic identity. Hell, it does not even need to be a state. If someone were to go on about how much they hate the beliefs of Islam, and how bad the religion is, you would decry that person as a racist person. That is because Islam is not just associated with a set of beliefs.
This makes so little sense as to be incoherent. The fact that your logic is dumb should be immediately obvious to you when it boils down to you declaring I cannot criticize a government without criticizing a religious and ethnic group as well, even when it is my explicit intent not to.
If I say 'I dislike what Israel is doing' you're saying that means 'I dislike what Jews are doing?' What about American Jews, which are actually more populous than those in Israel? Do I dislike them too? If not, why? After all, I'm criticizing Jews by criticizing Israeli policies. If I am criticizing them as well why would it hold that I am criticizing people for Israeli policy who have no control over it? Seems awfully mean of me.
Same holds true for Islam. If I criticize Iran or Saudi Arabia by your logic I am criticizing Muslims. As per your logic that in that case I am criticizing all Muslims, meaning I am attacking Indonesia by going after Saudi Arabia.
Take a step back and think about how logically absurd your position is. After doing that, do you wish to revise your declaration that you cannot criticize the state of Israel without criticizing Jews as a racial and ethnic group?
