I enjoy Arthur Sido's writing because he isn't afraid to tackle difficult issues. Arthur speaks frankly and "calls a spade a spade." Because of this style, some people will not like his blog. I, however, find it refreshing.
Additionally, Arthur is a Christian homeschooler with eight kids. That is impressive (he must have an amazing wife). I appreciate his perspective on home education.
Finally, Arthur holds some views on the church that will not be popular in most of American society. I don't even agree with everything he writes. However, Arthur desires to be biblical and challenges much of cultural-traditional church in the USA. It makes for interesting and challenging reading.
