Your reasoning is that if we look at the history of North Korea we will see that it has been a dictatorship since its inception, and similarly if we look at the history of Brazil we will plainly that it has not in fact ever been a republic and this is evidenced by the fact that Twitter is blocked?
I do not understand the impulse to evoke a completely unrelated thing to try to make a conceptual argument against a fact that you do not even attempt to directly refute. Brazil does not have a monarch. If you believe that Brazil is a monarchy, I encourage you to expand on what you think a monarch is both in terms of power and historical context.
