My take? Each person's home is is or her castle. It isn't up to me what is allowed inside. (In establishing that "castle", that person will have to deal with a landlord or neighborhood restrictions or mortgage company, etc. None of that is my business.) Honoring the rules of that castle is my obligation just like I expect others to honor mine. Calling ahead and asking about bike parking just isn't that hard. Don't have a bike you can safely park outside there? Well, we make our choices and get to live with them.
