I was confused, so I rowed over. HH's post was dated yesterday. So, he wants everyone to call Walmart on Black Friday and ask if they're open. The busiest shopping day of the year. One of the provided answers is "no." (he says a low-level manager would be manning the phones, telling the throngs that they're not open on Black Friday).
Then, he says that this activity (provided enough DUmmies do this phone stunt), will support the oppressed workers, by making it "go up to corporate."
I dunno. I'm seriously speechless.
