Serious question about the use of the word "fundie" [View All]

[Frogtutor]

I've noticed lately that the term "fundie" may be offending some of my fellow Christians. I am a Christian, but I'm also guilty of using this term a couple of times in the past.

I have used it to refer to one of my sisters-in-law who is an over-the-top, narrow-minded, judgmental, hypocritical, right-wing, fanatical zealot. That sounds really bad; I do love her very much, but she is quite messed up in the head.

Frankly, this is the exact type of person I thought the term "fundie" was supposed to refer to, so anyone who may have been offended, please forgive my ignorance.

I'm not a fan of labels, but they are sometimes a necessary evil in keeping communication manageable. I certainly do not want to offend anyone, so my question is this: What is an acceptable term to use when referring to these type of people?
