I like how you use “she” instead of “he”. Very politically correct. But still biased. Why not use “they” instead? It’s gender neutral.
Anyways, there are many reasons why people want other people to agree with them. One of them is that agreement reduces social friction. In other words, you can more easily achieve your goals. With that in mind, consider someone who wants others to agree with him merely because such an act would promote the attainment of his goals. Would you consider him an absolutist? I don’t think it would be appropriate. To me, an absolutist is someone who thinks that thare are infallible opinions. In other words, opinions that can never turn out to be wrong. Being a absolutist is similar to being a dogmatist, if not the same. If you’re trying to force other people to adopt your opinions that does not necessarily mean you think your opinions are infallible. It could simply mean you are trying to achieve your ends.
The distinction between “one of us” and “one of them” exists because people are different. Those who are similar to me, they are “one of us”. Those who are not, they are “one of them”. You two are making the same exact distinction. Those who think like you, they are “one of you”. Those who don’t, such as KT folks, they are “one of them”.
However, what you’re saying here is probably something more along the lines of “one of us (who know what is absolutely true)” and “one of them (who don’t know what is absolutely true)”. But I think that’s not a defining characteristic of absolutism. That’s merely one of its consequences. It’s what follows. The defining feature is the stance that there are infallible (a.k.a. absolutely true) opinions. If you think there are opinions that are absolutely true and opinions that are not then it follows that there are people who have absolutely true opinions and people who don’t. And if you think that your opinions are absolutely true then you would consider yourself a member of the first group (i.e. the rational ones) and all others who disagree a member of the second (i.e. the retarded ones.) The members of the first group would thereby be “one of us” and the members of the second “one of them”.
