"Nice" is a stupid word

According to dictionary.com, the word nice has origins of a detrimental nature:

Nice [nahys]

–adjective, nic·er, nic·est.

1. pleasing; agreeable; delightful: a nice visit.

2. amiably pleasant; kind: They are always nice to strangers.

3. characterized by, showing, or requiring great accuracy, precision, skill, tact, care, or delicacy: nice workmanship; a nice shot; a nice handling of a crisis.

Origin:

1250–1300; Middle English:  foolish, stupid < Old French:  silly, simple < Latin nescius  ignorant, incapable, equivalent to ne-  negative prefix + sci-  (stem of scīre  to know) + -us  adj. suffix

—Usage note

The semantic history of nice is quite varied, as the etymology and the obsolete senses attest, and any attempt to insist on only one of its present senses as correct will not be in keeping with the facts of actual usage. If any criticism is valid, it might be that the word is used too often and has become a cliché lacking the qualities of precision and intensity that are embodied in many of its synonyms.

As you can see, it originally meant foolish, stupid, silly, simple, ignorant, and incapable.  Furthermore, according to this online resource the word nice “has become a cliché lacking the qualities of precision and intensity that are embodied in many of its synonyms.” 

"I am sure," cried Catherine, "I did not mean to say anything wrong;but it is a nice book, and why should not call it so?" "Very true," said Henry, "and this is a very nice day, and we are taking a very nice walk; and you are two very nice young ladies. Oh!It is a very nice word indeed! It does for everything." [Jane Austen,"Northanger Abbey," 1803]

Even in this modern day and age, when individuals say things like "she's a nice person", "I am trying to be nice," etc., there is no meaningful concept behind their words.  In fact, this word always begs an explanation.  “She is a ‘what kind of' person?”  However, substituting other words make the same exact sentences mean something definite:

"She is a pleasant person."

"I am being merciful."

"My grandma is loving."

"He is forgiving."

"I am being generous."

Lastly, the use of such a vague word makes a weak sentence, argument and statement.  It is a indicator of either a poor vocabulary, or the a cover up for some sort of lack, disinterest, or an excuse coming.  It is a vague feel good word, not a virtue. 

Words such as: kind, honest, understanding, merciful, patient, forgiving, generous, thankful, and loving, are words that describe virtues.  These are action words and are very meaningful, giving the reader or listener an accurate picture of what is meant to be conveyed.

I vote that the word nice goes back its original meaning in common usage or it disappears entirely.
