A downward dove isn't of itself "satanic." A depiction of the dove that alighted on Jesus as he emerged from the baptism of John obviously has to be a downward dove. But, agreed, the usage of it here is blasphemous.
But even when it's descending the head is usually pointed upward isn't it?
Anyway, agreed. Even that in and of itself is probably not Satanic. I don't know that I could say the same about the triangle though.
