If the "star" was indeed from Satan, who (besides some nincompoop perhaps) would want the consarned thing inhabiting the very highest point on their Christmas tree? For a person to glorify a tool as used by Satan in an attempt to kill Jesus is certainly not a way to honor the person whose name is found in the celebration of "Christmas".
By that reason, since the bread and wine are symbols of the murder of Christ (for which all humanity hears collective guilt, BTW, including YOU) we shouldn't be referencing THOSE things either. The reason we do is because the murder of Christ was turned by God into the greatest victory for Good in the history of mankind. And the star is placed on top as a symbol that even our Misleader cannot ruin God's purpose for all of us. That's even if you think it's from Satan. I don't.
And who are YOU to suddenly pop up and say that Christians need to change the way we've been doing things for two thousand years? Suddenly a moral high horse appears out of Heaven for widdle bitty Schizzy to ride?
Strain the gnat, schizzy, and gulp down those camels...
