neb:Journeyman:Isn't that making the same generalisation based on appearance that others are making based on race? (Unless "burly men wearing ankle bracelets" is a dogwhistle for something specific).
From time to time I see burly men wearing ankle bracelets at that supermarket. They're not Fitbits either.
I suspect the ankle bracelets being referred to here are the court ordered kind. Not a jewellery choice denoting membership of a particular community (like hot-wives).
