“The Party told you to reject the evidence of you eyes and ears.”
The Department of Labor has just posted its second Nazi slogan (in the original, "Germany for Germans") in the last two days.
No one believes this is a coincidence.
They are telling America exactly who they are and what they intend.

All the latin speaking Soccer/Football nations should boycott the US World Cup right now. If we don't even follow our own laws we obviously will ignore the international ones. This makes us a rogue nation. Make America Great, my ass. He has turned us into a damn untrustworthy POS

All of the cities where I trained (undergrad, grad school, postdoc) were places with excellent public transit and bicycling infrastructure. I knew I could never afford a car as an undergrad or grad student. But non-car transit options made these opportunities possible.
public transportation was one major reason I went to grad school in San Francisco over some other choices. I knew I couldn't afford a car on my stipend. It was also a potent lesson on where accessible public transportation, like BART, is allowed to go (SF and the Easy Bay) and where it isn't (Marin)
When I was a new graduate in the year of our economic catastrophe 2008, I lived in NYC. Which was similarly great because a Metrocard is a damn sight cheaper than a car, gas, and insurance. Public transportation is for class and racial mobility. Which is why Americans are poisoned against it.

As the US hits a 33-year high in measles infections, there is now a "race" to find a treatment for the disease.
