Myriad, the point is that it is terminology used by racists as a dog whistle. One should be aware of the connotations of one's language.
I thought the whole logic of the "dog whistle" conspiracy theory was that the language in question doesn't have the negative connotations--that one can use it in public discourse with no one being the wiser.
The only people who are supposed to be able to hear and decode the signals are a hypothetical group of people who are specially tuned to a frequency nobody else knows about, and who are holding a code-book nobody else has ever seen.
In reality, the only people who can reliably hear and decode dog-whistles, are the people who are quick to accuse others of using them.
