All who care about liberty, law and human rights need to pay close attention to Airbnb’s actions. The short-term rental company is demonstrating how modern technology can become a grave threat to freedom itself. Notice that political belief is not included in Airbnb’s statement. It sounds as if Airbnb hosts are free to deny rooms to anybody traveling for political reasons. Under those rules it perfectly okay to deny a room to a union organizer, a pro-life activist, a pro-choice activist, an animal rights activist, a socialist, a civil rights activist, a peace activist, an environmentalist, a representative of the National Rifle Association, a member of the Flat Earth Society, or a person in town for a Democratic or Republican Party event.
