It would seem that these days politics is not about persuasion but about bullying. More and more we don’t say, “I disagree” with someone. We call them an idiot or a moron. Maybe the point is to turn as many voters as possible off so that the extremes can own the stage. I don’t know.
In discussing political positions one can have disagreements and still maintain a civil discourse. Akin's blunder wasn't one of policy however, it was one of biology where the facts are clear. Women cannot somehow prevent themselves from getting pregnant if they are raped. Legitimately raped or otherwise.
Since Akin believes they can, he is obviously an idiot or moron. It's true one can be civil in pointing it out, but the point must be made. He is not remotely qualified to represent anyone in congress.
