Lack of decorum is basically why libs hate Trump. He doesn't sugar coat what the empire does, and doesn't try to spin it as anything moral. He just comes out and says that US occupies Syria to steal oil for example.
This is his cardinal sin in their eyes, he pulls the curtain back, and it makes them really uncomfortable because he doesn't leave any ambiguity that can be rationalized away to keep pretending that US isn't an evil empire.
A dead famous populist leader in Canada called Rob Ford also had the honesty about the real culture of laziness, profanity, and alcoholism of European immigrants who became spoiled from the free stolen land, free child labor in Indian Residential fake schools, free stolen inheritance from abducted children, free misappropriated funding from state-swindled Indigenous parents, and high quality healthcare from free unethical experimention on children in fake school death camps. The free stuff that the ungrateful European immigrants received from First Nation people in Canadian Residential fake school death camps might even continued today although they need to supplement the Indigenous babysitters with exploitable immigrants of color to sustain the parasitic lifestyle of European immigrants.
