Historically, attempts to ban or limit the celebration of Halloween have pretty much been minor, isolated ones where a house of worship made some noise about it. Or a neighborhood association put formal limitations on the hours allowed for trick or treating.
But now municipalities in MA are getting on that bandwagon, as two school principals there decide Halloween has to go, because is not "inclusive" and can be "difficult" for some students. In one it will be replaced by "Black and Orange Spirit Day" and the other by some vaguely defined "community day event" in November.
Thankfully, the municipalities involved in banning Halloween do
not include Salem. The local chamber of commerce there would have a collective heart attack if anyone even hinted at the idea of "cancelling" that holiday
