“If you’re not happy here, then you can leave.”

There you have it. That’s the view of the president of the United States of those who have the temerity to criticize government policy, who seek radical change, who believe the government needs to do a better job for all Americans.

Donald Trump has doubled down on his racist Twitter rant against four congresswoman who have been highly critical of the government.

They are Alexandrea Ocasio-Cortez, Ilhan Omar, Ayanne Pressley and Rashida Tlaib. What do these women have in common? They are women “of color.” That’s it. Oh, they also are all U.S. citizens, three of whom were born in this country; the fourth congresswoman, Omar, is a naturalized citizen.

Trump said they all could return to where they came from and fix the problems there. That, I submit, is one more testament to the stupidity that the president exhibits with shocking regularity.

I’ll make one final point: This nation was founded by dissenters. Its very first constitutional amendment speaks directly to the rights of citizens to seek “redress” from their government.

Trump doesn’t get that. He needs to read the U.S. Constitution. He needs to come to grips with its meaning and the philosophy that led to its ratification as the governing framework for this great nation.
