One of the mistakes superficial efforts make is thinking respect means being nice and avoiding anything that makes people uncomfortable. Any sensible lean effort doesn't make this error (though I do think even good efforts are too worried about making anyone uncomfortable - at least in the USA) but many lean efforts do (many "lean" efforts are not very sensible, sadly).
