It is deceiving to play that way with definitions - however it is necessary to prevent the unknowing from really discovering what they DO mean.
I think you are describing the "doctrine" of providing "milk" to the mark, and when the candidate has been sufficiently duped, then they get the "meat" where we discover "only begotten Son" really means that Jesus had a brother called Lucifer. How they explain away this is that the "Heavenly Father" allegedly is "the father of the spirits of all mankind", so Jesus and Lucifer are "spiritual sons".
The real disturbing thing is, the apologetics for the Jesus and Lucifer brotherhood is made by them from Acts 17:28-29. To the biblically ignorant, the quote "For we are also his offspring..." makes it sound like Paul agrees with the concept of "spriritual brotherhood". What the deceiver doesn't tell you (because they somehow deleted that phrase when quoting it to you) is the part where Paul, while speaking to the Greek idolators says about that quote "as also some of your own poets have said". That is, the quote from which the LDS tries to sell this garbage is by quoting Greek idolators concerning their relationship to gold, silver and stone idols. IOW, the LDS gets their doctrine straight from pagan idolators and they wish to attribute this to the Creator of the Universe. Utter blasphemy.
Its just demonic. I wish they would go back to the days not all that long ago when they distanced themselves from the name "Christian".
Yes, that is one way of putting it. But it is a little different here where we are, shall we say - a little smarter than the average bear. By hiding behind those 'definitions', they are able to mentally deflect the question, rather than giving a thoughtful response to the question - at least in my experience.

Cults - particularly those trying to mimic Christianity - will always take the passage of scripture out of context to contort the meaning to fit their doctrinal twist. Throw in their own 'prophets' teaching and wa-la, their doctrine.

I wouldn't be too hasty on that aspect. The world is different today, and with the internet mormons are being exposed more and more to the false foundations of their faith. There are many here in the RF that are ex-mo's because they finally thought they'd prove us wrong - and end up with the Holy Spirit leading them to salvation in the TRUE Jesus. I prefer they keep trying - provides an object lesson for the lurkers reading the posts so that they won't become the easy 'mark' for the missionaries, knowing what they really mean.
