I do believe the vast majority of Christians on that Facebook page did not and will not behave like that 'poser'. And I do thank the the originator of the page for removing the inciting posts too. But it may be that damage has already been done. A seed may have been planted. There may be some less disciplined Christians who think what was proposed is a good idea. Now it is our duty to be alert for any rumor or talk of carrying out such actions. If such talk does arise we must open a dialog and convince all that this is not the right path.
