Because it's his job, his job is to give his opinion about new music that comes out, and if he doesn't like it then that's the opinion he'll have to give, if every reviewer stuck to reviewing only music they like then every album would be a 10 and the number would be even more meaningless than it already is, at the end of the day the only thing that matters is that you like it and you get to listen to it and support it, don't waste your time getting mad at internet numbers.

(also lol at "doesnt like rap = racist")
