but he didn't say, 'hey Joe Blow, shoot up a bunch of immigrants!'
Nor does he have to. This is why the POTUS has to be especially measured in the things he says.
For example, when the POTUS made the stupid comments about Charlottesville, white supremacy groups were fawning and salivating over his comments. To me his comments were not that bad, but they were stupid enough, that it gave fuel to the hate of his audience.
This goes against this idea that having a president who thinks and speaks with the carelessness of an average Joe on the street, is somehow a good idea.
