The problem is that this is all actually very murky, and at some point someone is going to sue an AirBnB host for discriminating. There's a lot of people saying stuff here, but ultimately liability will be judged and assessed by a court when a case comes up. And to be honest, a lot of these renters are going to look a lot more like independent contractors than anything. All it will take is one case and judgement against the host, and AirBnB suddenly looks even less attractive. Bad enough your house can get trashed, but for you to lose all your profit having to defend yourself in court or settle out of it won't make it attractive.
