black customer: hello, i would like to give you money to buy the things you are selling here.
white store owner: GTFO because you are black
rob roy: good use of defensive force, white store owner. very justifiable, peaceful, and proportionate. that black man was using offensive force to rape and enslave you. you fostered civility with your defensive force.
If you owned something, is one of the characteristics of that ownership being that the person who owns that something also holds the final say in the who can use it ?
If a person of the same race or a different race than yours, prefers you not to be on their property for any reason, what creates your right to defy their wishes if they own the property and you don't?
The way that you are presenting it, it almost sounds like you think in at least some instances, you would deprive a black person of their right to control their own property and that you'd force them to serve you against their wishes. I don't think it's right if you would force a black person to serve you, if they preferred not to.
Why would you force a black person to serve you, are you a racist ?
