Well, this proves that you are full of shit. Literally none of that is true.
The common modern edition of The Hobbit differs somewhat from the first edition because it was revised by Tolkien to fit better with The Lord of the Rings (most famously by changing it so Gollum doesn't wager the ring in the riddle contest with Bilbo, but he also removed some modern-day references). It has not been abridged or edited to make it easier "for modern readers." (It was always a children's book.)
TLOTR has gone through several editions in which Tolkien made small tweaks and fixed some inconsistencies and other errors and typos (later editors have also made further corrections, mainly to things like punctuation and capitalization). But these are very minor changes: the book reads substantially the same as the first edition. It is categorically false that it has been abridged or changed because it was "deemed too difficult for readers."
The Silmarillion is the one book "by Tolkien" that actually has been been extensively edited and abridged, because he never finished writing it: it was pieced together (with edits and abridgments) by his son, Christopher Tolkien, based on lots of different, inconsistent manuscripts. There is no unabridged version, but most of the separate sources have been published in the History of Middle-Earth series (+ Unfinished Tales), which collects Tolkien's incomplete drafts, again edited by Christopher Tolkien. (Christopher also edited standalone, longer versions of some of the major stories included in the Silmarillion.)
Tolkien wrote different books (and unpublished stories) in different styles and for different audiences.
Do you not even notice that you're contradicting yourself, or are you a troll?
