It's sad/alarming that, in this country, a president actually needs to address concerns of socialism (although maybe it has happened in the past, I don't know).
For years, Democrats have denied that they are socialists/communists, with the exception of a few such as Sanders. Only recently has the idea been embraced--starting with Obama and picking up steam with AOC and the new crop of socialists.
Still, many try to thread the needle, calling themselves "Democratic Socialists" as if there is a difference. There is not. Socialism is socialism is socialism.
Of course, the old order, Pelosi, Schumer, and the rest will still try to hide who they really are as they are more politically savvy than the moron from the Bronx and her hysterical loon sidekicks. They know socialism won't fly with the mainstream. Which is why Trump's calling the socialists out was such a brilliant move. We now have, on video, American politicians not embracing, even scowling at, the statement "America will not be a socialist country."
This not only helps to drive a wedge between the new and old Dems, but highlights this for all of American to see.
It was a good SOTU, but a brilliant move in that one part.
