I sincerely request that you step away from the keyboard until after valentines day

So first off I don't live in a country that celebrates halloween, so I might not understand all the hubbub.
I do however have kids that have attended school with less fortunate kids. So I have it ingrained in me that I don't want to alienate said kids. It's not a matter of telling you not to do what you want, it's a matter of the poor kids being able to go to school without being bullied.
As I tried to indicate in my original comment, I think it's overreaching of the HOA to do this, but it may actually come from the right place.
Anyway why do you need to get so upset?
