Any time that someone starts a sentence with, "I feel that...," I assume that he or she is about to express an opinion rather than a feeling.

Feelings are pretty basic; rage, joy, and grief are feelings. Most other things that people "feel" are opinions.

A true story: many years ago, a member of my family told me, "You should respect my feelings, and I feel that you should wear your hair differently."
