You are the one who will have to decide whether you should or should not hate the KJV, and the reasons for your choice. "Hate" is not a word I would generally use even in describing translations that I do not think are good translations. This sounds at least like a mild dislike:
Personally I do not understand how a Christian could dislike (even mildly) the KJV, the ESV, or the NIV.
I understand disagreeing with the direction the KJV took (in regards to the Anglican requirements/ committee edits). But all translations have similar external influences (whether athe Church of England, as with the KJV, or a particular translation philosophy, or a specifically tgeology).
But God has used those translations (and several others) to communicate His Word to people. To even mildly dislike God's Word because of an English translation is almost (if not exactly) blasphemy.
Today the KJV may be a barrier to some towards salvation, but God's Word is amazingly communicated through many translations and many languages.
I would hope all believers would rejoice in that.
