I think it's valid to criticise the existent of executive orders just as it's valid to criticise presidential pardons.....At least a system that puts them without number or limit as we see all presidents abuse them now.
However, we note that the people complaining now, were silent on both when they had a Democrat doing it......It was difficult to even get some of them to criticise Biden pardoning his crime family.
However, there is no dictatorship here, nothing Trump is doing is illegal and they are just talking utter claptrap. They might.....all of a sudden.....not like the US system but this has always been their system since way back.
