I’m not saying it’s right, or even mature, to refer to the Pee-resident of the United States as Cheetolini or the Tangerine Weasel, but I won’t tolerate people who spent 8 years calling President Obama "Obummer" denying someone’s Constitutional right to refer to the Drumpf as Herr Gurkentruppe.
So go ahead, if that is your desire, and say what you mean. Twitler. Trumplethinskin. Salmon Voldemort. Donny Tinyhands. You may not get much respect in sober discourse, and I won’t try to muzzle anyone, but beware to those who referred to Barack Obama by racist and belittling names who now suggest doing so in reference to the current occupant of the oval office is somehow too disrespectful.
