It's true that we don't usually use stative verbs with the progressive tense - note the emphasis on 'usually'.
As with most things English, there are exceptions. Some of these stative verbs can be used as dynamic verbs, depending on context. Normally this is to somehow emphasize an ongoing situation that's different from the past.
I think it's a case where students are given an over-simplified rule of "don't use stative verbs with the progressive tense", because the nuances of when it's okay may be considered too much information to a new learner.
I don't have any evidence to support it, but I do suspect that there probably is a trend towards an increase in using stative verbs dynamically, or at least an increase in which static verbs can also be made dynamic.
I also don't understand why anybody would be loving McDonald's food, but that's a separate discussion. :roll:
