Was this party B.Y.O.B.???

Shambles is absolutely right, he is NOT the problem here. He has an invitation, he has not been thrown out of the house, and he can continue to have fun.   We may not care for the way he gets his point across, we may not agree with his stance, but he is following the rules that have been laid down by the host.

If this WERE a party, many of us might walk into another room because we do not want to hear his stories again. There may be some people at the party who have such a grudge against Shambles, that they will go up to him and pick a fight. It might even go past name calling and get physical. At that point, the rest of the partygoers drop what they are doing to watch this fight take place.   The whole ambiance of the party has changed.

The party host can follow the philosophy that he or she said earlier - "Either way I am not responsible for THEIR problem and neither is anyone else", but that could be their downfall.   Perhaps the word "responsibility" is too much, but maybe not. If I let person D have too much to drink and he throws up in the fishbowl, oh well - we have a story to share at future parties. However, if person D has too much to drink and wraps his car around a tree after running down Sister Mary's 2nd grade class, then I am going to be sued as host for allowing him to drink so much. The host IS responsible in some ways for the actions of his guests and the actions they in turn inflict on others.

If one of my guests takes offense at Shambles sharing pictures of his summer vacation and takes a swing at him, I(as host) could find myself getting sued since the action to place on my property.   I may not take the swing, but I am in a position of responsibility for the party.

No matter what, the host is the ultimate reflection on how people look at the party.   You never remember a party by the name of the guest, it is always the host's party that you will refer to.   What action or inaction the host takes determines how people will view the party, and who will return for the next one.
