It was my understanding that the rebellion was the first show of force between white and black so against the planter class. After they been suppressed the ruling elite were afraid of such a rebellion is occurring again and introduced was that separated and stratified The races with different treatment under the law.
No not really but you can say it did contribute. The colonies were vast and dynamic places settled by different nations. New York after all was a Dutch colony, so there were many different cultures and ideas that permeated the discourse on race. In addition prior to Bacon's Rebellion, there were laws throughout the colonies that had already begun to differentiate slaves from the landed elite and free. For example Virginia passed a law in 1639 prohibiting slaves from carrying firearms. There are others and a quick search on my part turned up some interesting results. I am often loathed to refer to internet sources but in lieu of primary source material (I'm at work right now) check this out http://www.history.org/history/teaching/slavelaw.cfm
You can see that there was already and effort to separate slaves and differentiate them in the eyes of the law.
