While you'll probably get downvoted for this because it's not super politically correct, this is really a key point. It's uncomfortable but sometimes the biases are rational. IE there are subgroups that are more or less likely to cause damage. It can be quite unfair to many members of the subgroup. One option other than making it illegal is to socialize the risk. Airbnb could offer some universal damage insurance. This would at least remove the potential rational economic incentive for the property owner to select against certain groups.
