So how do your kids school Celebrates the Russian revolution

What part is not clear?

What your objections are.
You cannot say that it is not the time or place for something to happen and then claim you have no objections to that thing.
You state that it is one thing then claim you have never stated it is that thing.

Lets run through some again.
Why not celebrate the culture and not the war?
If you want them to celebrate the culture and not the war it implies you think they are celebrating the war(revolution)
I stated it is not the time or place for celebration of the Russian revolution
If you are saying it is not the time or place for it you are saying the performance was indeed a celebration of it.
They do not celebrate revolutions, wars or anything of a political nature.
So is this band celebrating those or is that a non distinctive distinction you make with it and your local bands?
performances in celebration of war, revolutions and political in nature do not occur at the local HS's
Same again.
The discussion concern celebration of a revolution and not a competition
I see nothing to object about unless the band played badly or the dancers were rubbish, apart from the traditional pre revolution peasant outfits which you equated with red army greatcoats do you have anything to say on the performance that doesn't hinge on it being a "celebration" as it appears that your comments all hinge on the idea that it was a celebration?
