I don't know that I would be eager to show up at a rally armed with my cardboard uterus with sponsors such as "This Slut Votes" or "Rock the Slut" vote.
Pro Life Action League notes that copycat rallies planned for April 28th hope to counter the tremendous success of the March 23rd rallies to Stand up for Religious Freedom that brought out 63K++ people in the middle of a work day in over 140++ cities across the US. I suspect their rallies will have to be held more in line with the local happy hours.
PLAL notes the panoply of the bizarre on their website. From mocking scripture...compliments of their religious choice sponsors to the pictures stating that science must be taught...wonder if they are against teaching the life begins at conception...probably not and to online sales of onesies for babies who survived the pro abortion mentality.
