Would it change anything if this was about couchsurfing (free service) rather than airbnb? If it was about white co-renters voting against new black tenants? What if I was traveling a lot and would let my friends use my car and/or stay at my house and all of them happened to be white? What if I was selective and refuse my best friend? Would it change anything if I asked for some kind of compensation? Compensation larger than to cover my direct costs? Is it business yet? I am selling a used item and cancel the transaction if the buyer is black. Does it change anything if I resell items for a living and do the same? I am not asking if this is racism. All I am asking is whether there is any difference between displaying discrimination in human to human interactions and human to society interactions. I personally hate this hypocrisy of treating sharing economy as business when it is convenient and sharing between individuals when it is not. Very similar to general opinion I happen to read about Uber: since it is "ride sharing", therefore most regulations are excessive, yet drivers sharing full time is somehow a norm.
