…the pro-abortion demonstrators attempt to surround and drown out dissent because they can’t stand for a voice of reason to invade their foot-stomping tantrum.… They see the possibility of losing their precious sacrament of abortion in some states, but not all, as a reason to stomp their feet, pitch a fit, and scream as loud as they can like petulant toddlers.
Grow up, Lefties!
