Activists are often stereotyped as being NF, or at least ExFx types, but I don't think this is valid. There are many possible causes and many ways in which one can be an activist.
I must admit I was disappointed recently when I was having a conversation with someone familiar with MBTI and they basically said that they were not/could not be an activist because they were an INTP (and not social enough). I must admit I was taken aback, but at the time I let it slide.
What are your thoughts on the relationship between activism and MBTI type?
