Oh please of Trump dressed up as a black guy for Halloween the entire left wing would shit themselves.
Why would they do that? Do you have proof?
Well there was that one time at band camp where a white girl did the same thing, and shit hit the fan.

No Trump in that story either.
Oh, I see what you're getting at. I actually have a name for this. I call it the rain in the desert fallacy. It's a fallacy that occurs when a person argues that a prediction is inherently invalid based on nothing more than the fact that the event has not been
precisely recorded in to have occurred at some point in history.
An example could be when a weatherman predicts rain in a normally dry desert, while a second person who has always observed the desert to lack rainfall rejects the prediction because neither individual has seen it before. The weatherman attempts to explain that his prediction is based on his knowledge of how rain is formed and when it falls, but the second person challenges that since the weatherman has never seen rain fall
in the desert he has no evidence that those factors will produce rain
in the desert.
The fallacy is in many ways a sort of meta-fallacy, where multiple faults in logic conjoin into a singular error. The person who invokes the rain in the desert fallacy demands proof that would ultimately be question begging; only when rain in the desert be established within an argument's premises will the invoker be satisfied to allow it as a conclusion. There is also a goalpost moving element at play. The weatherman can show evidence about how rain forms as well as evidence that the present conditions will result in rain, but the fallacy invoker demands a special degree of proof that the the present conditions will result in rain
in the desert.
