Does anybody else notice about the similarities between bdsm and the slave trade?

i'm gay and i kinda have a fetish for bdsm but everytime i would read about the slave trade with blacks being slaves it just turns me on for some reason. i just saw the movie roots and it was really erotic for me to watch. its like all the things the white guy did to all those slaves is what you do in bdsm. in a bdsm relationship you do physical labor, being whipped and treated like a slave, not to speak unless spoken too, not to look the master in the eye, and basically being treated like a piece of **** just like slaves in america were treated. am i the only one that notices the similarities between the african slave trade and a bdsm relationship?
