My comment had zero direction towards you, I don't believe I've ever replied to you one single time, instead you are the one that feels like I'm somehow talking directly to you. The only mod notifications I make are for spammers, because spammers can all fuck off and die. Touchy little fuck though, that much is apparent.
As for foreign injection into American politics, it happens every single day. There's many article and politician mention of gun control in other current and former UK countries about how they have gun control, that it "works" there, and we should have it here. That's a fact. So when another Brit comes to America and brings their shit concepts of restricting freedoms, because that's how they know life to be, we're going to take great exception to that and tell them to fuck off as well. The only thing worse than seeing someone with California plates move into town is someone with a limey accent. A couple-few generations, then maybe they're assimilated into American culture, but it is far from happening by an adult raising a right hand and making the citizenship oath because one can never rewrite their upbringing.
The UK has done well in suppressing their fake Freedom of Speech, that's a fact. The UK may not have ever had a right to bear arms, but they certainly acquiesced what little they did have with no fight. This condition of accepting what comes down from the palace and parliament is ingrained into the British culture. We see it in England, Australia, Canada, New Zealand, India, and many other smaller colonies of the Empire. You can say the Brits don't think themselves as subjects, I think the upcoming coronation ceremony will plainly show they all still feel them as subjects as much as the fanfare over every life event milestone of the now dead queen. A blind man can see they're still very much in the "subject" mentality to the crown.
The difference with America is we diverted away from traditional British culture early. The arduous lands, natives, and environment encountered by the early settlers throughout westward expansion, quickly ridding class as deciding factor of status even in the earliest settlements, is what laid the bedrock of American mentality differing from the native lands we came from.
As for "...assimilated... as anyone can get"? You're a soccer fan, I need not say any more.
