I don't think it was for no reason, there was a lecture he did and PRT and some of their peeps were there, and some of the peeps were challenging KRS, quite forcefully/rudely depending on your opinion and KRS responded. Also there was some philosophical differences when KRS was on the more humanist vibe and they were on the more 5 percent/nation of islam vibe. KRS was approached by some 5 percenters before and by a big dude that was with PRT. Anyway it got squashed, and Wize been supporting KRS movements consistently after that. They did Conscious Style too, which they paid KRS 15 G's for the verse.
No. That was after the fact. Krs-one randomly dissed them and called them "soft" in the Source magazine for no reason.
, out of the popular artists Nas always had the hardest subject matter.
