No chance I'd go to America, as they definitely check that sort of thing at the border now. Not sure how often that happens coming to the UK, yet.
I just went there as German and it actually went really smooth. They just asked me why I'm visiting and I said to visit a friend/tourism, took less than 2 minutes. So I think this is FUD
