I'm not so sure I follow you but...no one should have the "freedom" to anothers property.
Let me clarify - if the owners of the private property are offering their space for a fee, then it's not so private anymore, as they're maintaining a business. Therefore, they are to uphold the fair business practices (that should be) enforced in the U.S. Otherwise, their actions are illegal - regardless of which race is discriminating against which...
They weren't asking "freedom"; they were aksing for their "paidforitdom".
In case you didn't notice, they paid for use of the advertised facilities, then were denied actual use of said facilities. Notice that is no mention of any refunds for or price reductions for not being able to use the facilities for which they had paid.
Would you also agree that it would have been okay to lock them out of their paid rooms, and make them sleep in the halls? To lock them out of the dining room, after they had paid for their meals? Where do you draw the line?
