A blog in its very nature is an expression of opinion and personal stories. People come to your site to find out your opinion on various topics from child rearing to time off. Occasionally, you're going to get people that don't agree with what you say.
Maybe your vehemently against spanking or don't believe that television is that bad for kids and write something about it. These are hot button topics with avid supporters and detractors on both sides. The goal of many blogs is to get comments and hits. While I definitely agree that you should be able to approve your comments, don't just post the ones that support you.
