Forum:Spell canceller vs spiritualism

what is the current official Konami ruling on "Spell Canceller" vs "Spiritualism"? if there is no current official ruling, what say you? I figure "Spell Canceller" doesnt negate the effect of spiritualism, it simply PREVENTS a player from activating it in the first place, like Jinzo does for trap cards. yes?

thank you
