Yes that's one major reason why I'm puzzled as to why somebody would say I'm a Sensor. Ideas form the major basis for my own thought processes.
However, you brought up a great point about how many people would think so because of my staunch conservative views, which are stereotypically seen as SJ in nature. Yet again, as you mentioned, many Intuitives are conservative too. As even as far as my conservativism is concerned, my understanding of the concept is very much apart from the stereotypical image attributed to it.
INTJMom said I gave off a SJ vibe because of my strong interest in historical topics, but I highly doubt history is merely a SJ topic of interest

- especially since I'm very interested in the deeper meanings of history and what that means for mankind's future. So ironically, for me history is the key to the future.
There's also the common issue where I seem to give off various different impressions to people. This has lead to people making various different assestments of my character, and I'm very amused at how often they'll contradict with each other. I've joked that I'm pretty much whoever you want me to be.
People constantly tell me upon getting to know me better that I'm far different than what their first impressions conveyed. That happened with Amargith yesterday actually.
