Of course there is.
Let's take FR for example. I could type a response to you full of profanities and obscenities, which would be rude and unjustified. I am in my dwelling right now, and it is legal for me to do so.
However, it would effect you wherever you are and be a violation of the "community" rules in effect here. The OPINION that profanity is offensive is one that this community and its management has agreed is valid, and if I desire to participate in this community, I must abide by that opinion.
Fair enough. Let’s call it a law for our little FR world. We agree up front to the laws and understand what could cause our banishment. In the case of the "offending" owners, the rules were apparently changed to restrict their rights to use a legal product in the privacy of their home after they had purchased the condo. (Please correct me if I’m wrong) If we are banned from FR for any reason, we have not lost a necessity or lost any money. If these owners want to continue to exercise their legal rights, they would be forced to lose a necessity and possible lose money. To me, this is somewhat moot because I think the other owners should go after the constructor of the unit for cross-ventilation problems.
As for the hypothetical offensive response, I might find it rude. But I could also find it entertaining depending on how fluent in profanity you are.
