Freshmen congresswomen known as “the squad” promote some ill-advised ideas, from the Green New Deal to the elimination of private insurance to reparations for a horrible wrong that occurred more than 150 years ago.

From a policy standpoint, this strikes us as slightly more sane than storming Area 51.

We don’t suppose these members of Congress — Rashida Tlaib, Ilhan Omar, Alexandria Ocasio-Cortez and Ayanna Pressley — would win many elections in northwest Missouri. But our country is a diverse place, with voters in Detroit and Queens perhaps seeing the world differently from those in St. Joseph or Princeton, Missouri.

Is that such a bad thing?

This week marks the 50-year anniversary of the 1969 moon landing. Think about that: Just three decades after the Great Depression, at a time of social turmoil and strife in the United States, Neil Armstrong’s first steps represented one of the most significant achievements in human history.

This month has brought countless retrospectives on the Apollo program, but the more interesting perspective comes from those who witnessed the event back home. Those grainy images — narrated on CBS by St. Joseph’s Walter Cronkite — became a shared experience among people of all races and cultures.

Today, unity eludes us as much as a manned mission to Mars.

President Donald Trump utilized his Twitter account last weekend to sow divisiveness, calling on progressive Democratic congresswomen to “go back and help fix the totally broken and crime-infested places from which they came.”

This has stirred up a predictable storm on the left and right on whether Trump’s words were racist. It’s hard to tell if the president is racist, thin-skinned or just spoiling for a fight, but the chief executive’s words carry tremendous weight — more so than freshmen representatives — so this latest Twitter storm strikes us as both deplorable and counterproductive.

That’s not because we agree with these congresswomen, quite the opposite, but because of the unnerving implication that those with different backgrounds, beliefs or ideas are somehow un-American and don’t belong within these shores. They do belong, and they are Americans. One can and should believe this despite strong disagreements on their past statements regarding economics, foreign affairs and more.

On many of these issues of substance — taxes, regulation and the need to do something about border security — Missouri’s Republican delegation has been right to stand with the president.

Now is the time for those Republicans — public servants like Rep. Sam Graves, Sens. Roy Blunt and Josh Hawley — to stop ignoring Trump’s Twitter feed as something your crazy uncle says at the dinner table and issue a public rebuke.
