I've lived in Leeds since I was 3. That's 19 and a half years in case you were wondering....and Leeds, as it happens, is VERY diverse.
You've got townies, chavs, rockers, goths, skaters, alternatives in general, upper class, middle class, lower class, people that like rock, people that like r n b, people that like dance trace techno stuff, people that like classical music, black people, chinese people, white people, polish people, asian people, french people, tall people, short people, medium people, midgets, clever people, average people, stupid people, people that like horse riding, people that are terrified of anything with 4 legs, people that like cinema, people that prefer staying at home with a good book.....
I could seriously go on all day.
What's NOT diverse about Leeds?
In fact, what's not diverse about any major city? All major cities are diverse!
I'm thinking that people who suggest that Leeds isn't diverse are clearly not getting out very much!
