In addition, all communication is context sensitive. When a politician who needs nei-nazi votes to get elected says something questionable, it's not unreasonable to assume it was intentional.
Just struck me that the term 'dog whistle' to the general population just means something you toot to get a dog's attention, whereas to a select target audience it has far more sinister implications and acts as a call to action of sorts. Ironic.
“dog whistle” comes from supersonic dog whistles that dogs can hear but humans can’t, not just whistling to call a dog. The analogy is that a speaker can use a phrase that most people won’t notice but their intended audience will understand.
Maybe you already know this and I misunderstood your comment.
Dog whistles are why we can't have nice things.
