JWs are self-loathing fundamentalists. By that I mean they are fundamentalists who try to put up a front of moderation and pretend that they are reasonable.
This is clearly seen in their view of the word "Creationist." They scorn the folly of young earth creationists and hide from the reproach and shame of creationism by dishonestly denying that they too are creationists.
To hide from the fact that they too are creationists who believe the equally foolish idea that humans have only been around for 6000 years, they dishonestly play the word game of redefining the word creationist to refer exclusively to young earth creationists.
It's a fundamentalist cult that works hard to present a public image of being balanced and reasonable. They even trick themselves into thinking that they are balanced and reasonable! And it's all done by the use of deceitful linguistics and crafty fallacious reasoning. Example:
"Oh we don't shun members who leave! We just don't associate with them as much because we don't share common interests. They are the ones shunning us! They are the ones who wrote a letter saying they don't want anything to do with us!"
