Was the musical "Hair" racist?

I guess because of friends and relatives who came of age in the 60’s, I have a terrific interest in the decade and the so called “counter culture”. The Vietnam War, campus unrest, race riots, the Beatles etc. I like reading about the whole thing.
A musical was produced at the time, “Hair” that caused quite a stir because of sexual references, drug references, and nudity.
A couple of the songs in the original play contain language and/or metaphors that could not be printed today without generating controversy at best and censorship at worst. In fact, I figure I can not write the lyrics without getting modded, so I will not. You can look them up.
Are the lyrics to Colored Spade, and Black Boys racist?
If not, why not?
If so, how did Hair get to be such a popular counter culture statement?
