While true, a lot of older people in the UK get really, really racist when it comes to their bloodline. Some people view themselves as more British than others because of their lineage towards the Saxons, as opposed to people that have been here for 100+ years that may have originated from elsewhere. Many don’t consider anyone to be British if they emigrated from somewhere like Jamaica, India, or Ireland because, in their view, only the pure Anglo Saxons are the original Brits, even if 5-6 generations of their family grew up here, embedded themselves into society

I do agree that Americans are really weird when it comes to their ancestry, especially considering they come from a country that is very anti-immigration. IMO if you want to claim that you are 50% British or whatever, you shouldn’t be blocking British people from moving to your country (and vice versa).
