In politics, a dog whistle is the use of coded or suggestive language in political messaging to garner support from a particular group without provoking opposition. The concept is named after ultrasonic dog whistles, which are audible to dogs but not humans.
Something to be aware of; however, is that it is also a
slippery slope fallacy in which bad actors can claim any one thing can also mean another thing without having to explain why logically. The counter to this is to ask them to explain how they came to that conclusion, to which, they won't be able to actually explain why logically.
Equating legitimate generalized statements or criticisms and concerns to hate is generally how the Dog Whistle
Slippery Slope Fallacy is abused by bad actors looking to put words or intent in their victim's mouths.
This also leads to a circular logic problem where the person injecting the
slippery slope dog whistling racist intent into the meaning of a generalized statement will claim everyone who disagrees with them are bigots, and they know they are bigots because they don't agree with their beliefs, therefore those beliefs are correct because all who disagree with them are bigots.
