Speaking only for myself (as someone who consistently scores on the far end of T), viewing it as a spectrum of F<->T makes a great deal of intuitive sense, and directly mirrors my personal observations. Just as I tend to quickly write off very emotional people as irrational, I suspect someone leaning strongly toward F would similarly write me off as a heartless bastard.

From your perspective, as someone sitting mid-way between the two, I can appreciate how that distinction might not seem as clear-cut. It's something I hadn't considered before; thank you for that.
