I will ‘defend’ when YOU can explain why your chosen religion thinks they ARE ‘necessary’.
LOL.
You have the same Bible I do.
No explanation necessary!
You flat out do not believe what your Bible tells you and that pretty much is the bottom line.
Welcome to latter day Christianity.
You flat out do not believe that what your Bible tells you is adequate, and that much MUST be added to it to get the 'correct' doctrines from Joseph Smith.
Can't rightly blame the BoM though - as it fairly states what the bible already mentions.
However, the bulk of the NEW things that LDSism adds comes NOT from the BoM, but other LDS scripture.
The BoM doesn't state how the garment is to be designed or worn.
The BoM doesn't contain any sacred covenants that LDS members must avow to to be allowed into an LDS temple.
The BoM doesn't describe differing levels of heaven.
The BoM doesn't... well - you know.
