All, thank you for the kind comments. I just wanted people to know about my friend.
As for the one who is unable to quench his desire to say something controversial, I would admonish the rest of the group, in the words of my best friend of my youth's mother "don't pay him no mind". If he chooses to go low he may do so, but don't let him sully Marty's memory by acknowledging him. There is a time and a place to discuss the politics of it all, but it isn't here.
