Commentator: Unfortunately, Roehmer' s opinion column has a polarizing effect on national politics  She has always taken a partisan stance, and lately she has taken the further step of impugning the motives of her adversaries  That style of argumentation is guaranteed not to change the minds of people with opposing viewpoints; it only alienates them
But that is likely not a problem for Roehmer, since her column is just an attempt to please her loyal readers
criticizes a column merely by invoking the personal characteristics of its author
