I agree with everything, but a quibble just here: a "dog whistle" is only supposed to be audible to the dogs. This is more like a steam whistle.
When Maggot Toxic Greede says, "We're big on our Second Amendment rights", even the deaf hear that tune loud and clear.
My first dog whistle was decades ago in the early days of the Internet when I was Internet dating. I talked to one woman who had a lot of phrases like "heritage" and "culture" on her profile which today would be a giveaway.
We talked on the phone for a minute and I said, "I'm sorry, I don't think this is going to work out," and she yelled something like "You bet!" and slammed the phone down - this is in the days of landlines.
Thanks for another strong, if depressing, article.
