If you think your Muslim government is committing blatant kufr, and you are finding arguments to prove that; you are in fact proving that it isn’t committing blatant kufr.. because the key word here is “blatant”.
What is blatant does not require a microscope to see, it doesn’t require argument; it is like the Sun; obvious to everyone and undeniable.
It’s not blatant if you have to prove it
