Idols of Mary are idols, but were I or anyone else to destroy one, faithful Catholics would just make a replacement. The goal should be for them to repent of worshipping idols in the first place. That takes persuasion and education rather than just brute force, something that thugs don’t have the patience for.
Catholics don’t worship Mary, statues, popes, or popeye.
Mistaken information there.
Pictures or statues are not idols. If that were true, then the pictures of your parents or children in your home would be idols.
You have parroted an anti-Catholic slander.
Catholics do not worship anyone or anything other than the triune God, like all other Christians.
Catholic statues of Mary, however, are not idols, because Mary is not worshiped. Unless you're against all statuary art, including war memorials, gravestone sculptures, historic and patriotic statues in Washington DC,the Minuteman, Lincoln, the raising of the flag at Iwo Jim, etc., etc. you really have no reason to be against statues of Mary.
