I can't see how the comment about Brighton was at all racist, albeit a lack of ethnic diversity doesn't chime with my own experience.
As to 'America' - what, the whole continent? As for disliking the US because of its brash commercialism, this is what I expected to find before visiting for the first time. The reality was that outside the major metropolises/tourist traps it was very far from that. I've been up and down the eastern seaboard on an extended road trip and met with all ends of the social spectrum, from the frenetic pace of NYC Times Square to the quiet, open spaces of Maine. Not all even NYC was overrun: lower Manhattan and some of the eastern region was far quieter than expected.
I did like Boston, but was staying with people who lived there which does make a difference. Likewise one of the quieter, lesser populated Florida keys. Loved the eastern US so much that I ended up staying to work there for a few years and once seriously considered settling permanently. It's a big continent. Like anywhere attitudes are diverse and sometimes unpaletable, but in general it has a vibe I love.
I have no great love for London. Top UK cities for me: York, Bath, Oxford, Edinburgh, and yes, Manchester and Liverpool. L1 is really impressive these days and the waterfront areas are quite beautiful. Areas topping my list of natural beauties are Dorset, North Wales, the Avon region and North Yorkshire.
As to the PP who doesn't like Windermere: Alesund on the west coast of Norway is a dead ringer for that place, and the beauty is it's nearly empty. The nearby Sunnmore mountain region is great if Cumbrian fellwalking is your thing. It has everything, if you replace lakes with fjords!
