Kendrick is at a point in his career where haters are going to try and balance out the massive amounts of love he's been receiving with shade, whether it be consciously or subconsciously. he's one of the better rappers right now. Dude obviously takes pride in his art instead of half assing it (respect), he actually RAPS (respect), helping to bring back the lyrical aspect to the mainstream (respect), brings something new to the table while going platinum (respect), has artistic integrity by not trying to milk that Lady Gaga feature (respect), boycotted the whole GQ magazine thing (respect), and he tries putting a message in his music (respect). He's putting in work, actually cares about hip hop, and is relatively humble while doing it, I don't see why wouldn't deserve the praise.
he dropped 2 of the best albums in YEARS and you ca nbe sure his third album gonna be even better. Will you liek him? probably not, but michael jackson, bob dylan and a lot of other goats also had people who didn't like their music
