The talents are Gods gifts to us all of them. If we do not use those gifts to His glory (His account in the parable) - then we are unprofitable servants. See also the parable of the sower.
The ears to hear are also gifts of God.
Why do ye not understand my speech? [even] because ye cannot hear my word. John 8:43
But ye believe not, because ye are not of my sheep, as I said unto you. My sheep hear my voice, and I know them, and they follow me: - John 10:26-27
Other references to fool such as the fool has said in his heart there is no God are not directed to another person but rather to a type of person. It is a judgment of matter v. people which we are to effect (I Cor 6, etc.)
Very, very Gnostic.
Ranting? You call showing you that Matthew says not all who call on Lord's name shall be saved, and Paul and Luke and Joel say just the opposite, ranting?
Please, show me why is Mat 7:21-23 "true" and Acts 2:21, Romans 10:13 and Joel 2:32 are not. If I rant, it's because everyone is pretending the emperor has clothes when he is buck naked. Wake up people!
However it should be noted that Jesus Christ certainly is within His authority as God to use the word fool without the penalty He speaks in Matt 5.
Matthew also says that whosever calls someone a fool is in danger of hell fire. When I show you that so many authors, especially Paul, call other people fools or foolish, you are dismissive.
This is not an issue whether Jesus is "within His authority" (or some other nonsense like that) to call anyone a fool. Of course it's "within His authority!" but He wouldn't because He would have to call everyone a fool! Yet, Paul, on the other hand, finds it easy to call some fools and some saints, insisting that some are better than others. That should tell you everything about that man and "his" gosepl, as he calls it (that is, the one he invented).
