Political posts, like other posts, are partly there to defend what I believe in, but they are also designed to generate critical thinking. I know this is a forum in which liberals and conservatives can enter the discussion. I also want people to realize that Christians can exercise some independence of mind when it comes to politics. I have seen this from both liberals and conservatives in the comment box.
When I talked about improving the tone of the discussion, it is important to realize that I mean for it to begin with me. I can't control Steve Hays or Ilion or anyone like him. I don't know what to say to people who think that anyone to the left of John McCain is an intellectually dishonest evildoer. I also don't know how to respond to people who think all Christians (or atheists, for that matter) are stupid, ignorant, insane, or wicked. That kind of certitude has always escaped me.
If my posts serve only the goal of political advocacy, they fail by my own standards. It's easy to hit easy targets.
