I tend to agree. fundamentalists seem to pull things out of a hat and demand that to be a true Christian you will do these things (in my circle it is usually head covering, dresses only on women , KJVO reading and never touching alcohol) The things they choose are man made, usually, and stretch the limits on Bible truth.
A conservative, they study the Bible, speak where it speaks and remanin silent on issues where we are given a choice, or where the bible says nothing.
My fundamentalist sisters are Christians, they just suffer from an over abundance of pride. It is that whole log and spec thing. Instead of focusing on their heart, where God puts HIS focus, they are focusing on the rules, where the phariasees had their focus, being higher and holier than others.
Mind you this is all my opinion, based on my observations from runing a Christian women's message board for the last 5 (almost) years.
