(1) As you know, every language has exceptions to the rule.
Nowdays, most native speakers have no trouble using the
progressive with some stative ("non-action") verbs:
I am loving/liking/hating this more and more every day.
(2) Your question reminded me of Mr. Jack Benny, who was a
famous comedian here in the United States. On his television show
one day, there was a scene in which a bad man holds a gun and says
to Mr. Benny: "Your money or your life!" (= Give me your money or
I will take your life.)
Mr. Benny (who always played on the radio and television a
person who did not like to spend money) did not answer.
The bad man became impatient and demanded an answer.
Mr. Benny looked at him and calmly replied:
I'm thinking!!! I'm thinking!!!
