So wait. Your answer on "Why is it bad to do something all kids can participate in?" is basically "Someone will be offended and the life isn't fair"? .
Key term in your realm:
ALL kids.
Again, you repeatedly focus on
ALL.
Well, here's the reality in school:
Can all children participate in all sports?
NO - some may have disabilities that don't allow them to, or they don't like particular (or all) sports.
Can all children participate in band or orchestra?
NO - because not all want to (or feel they have the talent and ambition to) take up learning to play an instrument.
Can all children participate in drama or musicals by getting speaking and/or singing roles?
NO - because there are not enough roles to accommodate everyone and some students have more innate or developed talent for that sort of activity than others.
Can all students participate in accelerated or advanced coursework?
NO - because some students learn faster or more substantively than others.
So there is no such thing in the school realm as your fantasy vision of "
all kids can participate in (insert subject). Including fabricated substitute "holidays" that inevitably still end up being un-inclusive. How so? Because in our present environment, it is almost guaranteed someone will feel some aspect of your supposed "
something all kids can participate in" event (the 11/9 William-Mitchell Harvest-Festival- Community-Autumn-Celebration-thing-whatever) is "offensive" or "incompatible with their values or preferences".
Heck, that could include families boycotting it due to their being annoyed at the cancellation of the Halloween Parade. Which if that happens should be a message to Principal Gregory Bayse about his performance in improving "inclusiveness" amongst the families his school serves.
And lastly, 11/9 is a school day. Why is time being taken out of the regular curriculum for some vague, amorphous "substitute holiday," one that for all we know may have no unique aspects that families and children couldn't enjoy on their own outside of school?
