Some people don't seem to understand what dog whistles are, or pretend not to understand.
All of these terms are distinct and relevant terms with different meanings that could be used to criticize specific concepts or individuals. If they weren't, they wouldn't be dog whistles, they'd just be slurs.
A dog whistle is intended to sound reasonable and specific to the general public, to give the speaker the shield of respectability and plausible deniability, but to people who subscribe to the same conspiracy theory they mean something other than their face value.
If someone uses a lot of these words, the words are more likely to be a nudge and a wink to the in-group than actual intended specific criticism.
