I honestly thought of putting this in the politics board, but I think that would've been very insensitive
Ok I'll bite - people that believe (
politically) in gun control don't think that this is offensive or insensitive; on the contrary, they feel they're properly commemorating the victims deaths by trying to avoid this happening in the future, and there's no better time to do it than when the paint is still wet.
And you feeling otherwise is because of your political beliefs. Hence: wrong board.
