Those remarks are inappropriate and should be retracted. We are all volunteers here. That means we give up our valuable time to help others. Moreover, you were given excellent answers here and in your other threads that, in my opinion, adequately address your queries. I refer to my replies in your other thread below.

If you'd read those carefully enough, you would have noticed my note that the present perfect can be used with stative verbs (e.g., "think" or "want") to indicate something that starts in the past and goes right up to (and possible including) the present. In fact, this usage applies to all the examples you cited in post #28.
If you want to go and ask linguists (as you put it), that's entirely up to you; but if you want to continue to participate here, we expect you to show appreciation towards our efforts. Remember: it costs nothing to be nice.
