As Sam Houston would point out, some people never learn.
Here is what then Governor Houston said in 1861 when presented with the Articles of Secession:
"To secede from the Union and set up another government would cause war. If you go to war with the United States, you will never conquer her, as she has the money and the men. If she does not whip you by guns, powder, and steel, she will starve you to death. It will take the flower of the country-the young men."
"In the name of the constitution of Texas, which has been trampled upon, I refuse to take this oath. I love Texas too well to bring civil strife and bloodshed upon her."
"I declare that civil war is inevitable and is near at hand. When it comes the descendants of the heros of Lexington and Bunker Hill will be found equal in patriotism, courage and heroic endurance with the descendants of the heroes of Cowpens and Yorktown. For this reason I predict the civil war which is now at hand will be stubborn and of long duration."
The patriotism of the Left is always called into question, but only the Right can really pull off sedition. Robert Hanssen was no liberal tree hugging hippy.
