A popular leftist meme is the following:
"Dissent is the highest form of patriotism."
It is commonly attributed to Thomas Jefferson, the Third President of the United States.
The problem is, he would never have said that.
In a letter to Thomas Pinckney, from 29 May 1797, he wrote:
"Political dissension is doubtless a less evil than the lethargy of despotism: but still it is a great evil, and it would be as worthy the efforts of the patriot as of the philosopher, to exclude it's influence if possible, from social life. The good are rare enough at best. There is no reason to subdivide them by artificial lines. But whether we shall ever be able so far to perfect the principles of society as that political opinions shall, in it's intercourse, be as inoffensive as those of philosophy, mechanics, or any other, may well be doubted."

The left cannot rely on anything but the legends they create for themselves. As the Germans would say: Geschichtloses Pack.
Translation: Ahistorical bunch, but in a rather pejorative sense.
