Your analogy you've used there is moronic! I responded civilly to a point made about history with regards to a minute's silence not being something that will improve the understanding of a historical event, because that was the very point that was being made. You cannot confuse an act of remembrance with historical learning, particularly if there is nothing else (like a talk, some poetry etc) attached to the silence.
Considering you aren't even going to be there, why are you making a such a fuss? If it means that much to you, move to Southampton and campaign for it. What did you do for the 99th anniversary of the sinking, or the 73rd?
