Morgan is a "subject"...
Americans are citizens -- there is a difference!
Go back across the pond...
....arrogant English prick...
And don't let the screen door hit you in the bum on the way out!
For the record, he isn't a subject - he's a British citizen. The argument you are using used to be true, but hasn't been for decades and should now be avoided because it opens up avenues to try and undermine the very valid points that are being made.
The term British Subject ceased to have legal meaning in the United Kingdom in 1982 - and Britons had been British citizens since 1949 (between 1949 and 1982, they were considered both subjects and citizens). There are a small number of British subjects left - basically refugees who were granted British subject status prior to 1949 and who don't fit into any other category, and some Irish born people born prior to 1949 who aren't entitled to Irish citizenship. They've been allowed to retain the status of British subjects, only because if they lost it, they would have nothing approaching citizenship status anywhere. No new people will gain that status and when the last of them dies, the status will cease to exist completely.
