Being of Scottish descent and having studied the history of the abuses that the Scots received at the hands of England both at home and in America, I have to agree whole-heartedly with your estimation of the Brits. The cruelty and arrogance that they ruled America with was the reason we kicked their arses back to England.
Study history better then. Because English and British are not the same. If you cant get that most basic fact correct, then....
And many ‘English’ abuses of the Scots were in fact done by Scots themselves. The Braveheart reading of history may be exciting, but is is simplistic to the point of being dangerous.
