I Cannot Justify Lyrics

I am a white girl but what was I before?
An Onondaga opening the door
Coulda been a pilgrim hungry for to pray
Or a roaming buffalo soon to fade away
[ Lyrics from: http://www.cloverlyrics.com/e66656-adrienne_young~i_cannot_justify_lyrics.html ]
Was I a little boy hiding underground
An angry soldier sent to shoot John Brown
Might have been red clay staining tired feet
Of a broken army suffering defeat

Let me grow from these clothes
That cling so tightly to my soul
How can I justify the narrow vantage
Of these eyes
Such a good disguise, I cannot justify

A hooded demon did I wear bloody boots
Did I fall like thunder torn from ancient roots
Black wing vulture peckin' heartbroke bones
Or was I an orphan born to die alone

I am a white girl but what was I before”
