Her being at the foot of the Cross has nothing to do with the post, but she WASN’T wearing the crown of thorns that our Lord, King, and Savior did. Only our Savior could wear those thorns as it was his Blood and Broken Body that purchased us back from the curse of the original sin. As noted in Genesis Man’s sin caused the cursing of the ground which caused thorns and thistles. He wore the crown because the Romans mocked him as King (his only charge), but it was no accident that it was made of thorns. As sin entered through one Man Adam it was taken away by one Man Jesus Christ. Your posted pic absolutely proves the OP’s point that Catholics worship false idols to include Mary.
BTW, your posts make absolutely no sense, at all.
