Do you use AirBnB? How about I claim there is a rally in any city you want to stay, or complain to AB you are hosting ebil racists and get you blacklisted?
Is it just a claim though? It seems quite factual
You aren't worried that Airbnb's net will catch innocent people? For example: Journalists covering the rally, or counter-protesters.
These people weren't hiding anything about their position on this matter. So no, not really.
