i quite enjoyed "Electro Glide in Blue" as it's a fun mix of styles from blues to ambient to rock. "Gettin' High on your Own Supply" has a lot of energy and some great sountrack-y instrumentals, as well as several corny but enjoyable bigbeat cuts. i haven't heard their first or latest LP so i can't comment on the lyrical content you mention. But remember they also had a track with a vocal about putting one's hands around a white man's throat, so i don't think they're being supremacist.
As an aside, the album art of Prodigy's "Fat of the Land" says: "Would you rather have butter or guns? Preparedness makes us powerful. Butter merely makes us fat", which was stated by Hermann Goering, a nazi general. i don't remember this causing any controversy whereas "Smack my bithc up" made a stir.
