Racism? Yep, we can make that a public health issue. The CDC will even defend such a decision, saying that racism is dangerous to the public's health (I wonder how they feel about communism). [source]
We don't view crime as a public health issue. Nope. Guns are the problem. We need to label them as a public health threat as well. [source]
Masculinity? Yeah, we can make that a public health threat too. [source]
Climate change? Why, yes! Absolutely! [source]

Doctors and hospital administrators refusing to treat patients are the true threat to public health.
