Wouldn't totally agree with that. Music made in current times are viewed differently than music made 20 and 30 years earlier
Back in the 80s and early 90s, those Pro Black song were not viewed the same way as they are now. Most of their songs were not all over white Top 40 radio that much. Russell Simmons even said something of wanting them to tone it down. Plus, KRS One, X Clan, and Brand Nubian never got that pop culture fame when they were in their prime. Public Enemy only got fame because it was through Def Jam, Rick Rubin, Russell, etc.
Public Enemy and KRS One can perform those songs now cause it's thought of as a old school novelty. Look how up in arms the media was for Beyonce's lightweight Formation video

. You really think this racist PC world we live in now would even promote X Clan, KRS One, and PE if they were new artists in this era? Nah breh
