I don't use google. to Fascist for my tastes. On bing, (also fascist, but most powerful competitor) the second entry says this:
The Union Jack, or Union Flag, is the national flag of the United Kingdom. The flag also has an official or semi-official status in some other Commonwealth realms...
Your google-fu is weak grasshopper.
Let me guess, your next argument will be that the Colonies broke away from the British Kingdom in order to preserve their "peculiar institution".
My argument is that it doesn't make a d@mn why they left, it is the fact that they had a right to leave for whatever reason d@mn well suited their fancy.
That whenever any Form of Government becomes destructive of these ends, it is the Right of the People to alter or to abolish it, and to institute new Government, laying its foundation on such principles and organizing its powers in such form, as to them shall seem most likely to effect their Safety and Happiness.
It's called being "free" rather than "subject" to the will of others.
And you really should stop defending King Georgie. He didn't consider the matter settled, he just took a break to defeat Napoleon at Waterloo.
The Colonies were obviously lucky to have a powerful military force occupying the Union they were leaving, but the Confederates didn't have such luck.
Unfortunately for the United Kingdom of the British Empire, when they did have time to send the Greatest Navy in The History Of The World to finish up the pesky little matter of those uncouth american rabble-rousers, they ran into Old Hickory.
Virtually the only battle we won in that conflict, and that after the war had been long over officially. Again, had the British been as fanatical as Lincoln, we would have been made once more part of the United Kingdom. We got our @$$e$ kicked in that war.
Come to think of it, now I am not even sure if Old Hickory considered himself a northerner, a southerner, or just plain an American.
Well, he owned 200 slaves, and ran a plantation in Alabama and another in Tennessee. For his time period, that was pretty American all right.
Doesn't cut it and you know it. You're making up stuff, fabricating it out of thin air. Link me to "British Union", or stop using the term. Bing, Google, don't make no never mind to me. Link it, or stop using it. "British Union".
