The problem with this question and some like it is that degrees of what and how Jehovah's Witnesses "believe" things are all strange, weird, and sometimes just downright wrong.
When I was associating with the Witnesses, some of them believed that the mere musical theme of the Smurf's television cartoon on Saturday mornings was demonic.
Others believed that some non-Witness homes would remain standing after Armageddon, and they would purposefully check-out terrorities that included the real estate of houses they would like to live in, hoping they could interest the householders to conversations that would invite them in so that they could get a glimpse of the place. If they liked the home, they would ask Jehovah to spare it so they could move into it after the Great Tribulation and the householders had died.
Others avoided Oreos because there was a rumor that blood was being used by Nabisco to make them, and of course the Bible prohibited one to consume blood...
Not official beliefs, of course, but ones that shaped how they filtered what came down the Watchtower pipeline and how they applied it.
I could go on, but you get it. This should be enough.
The religious foundation of Jehovah's Witness thinking is more than strict theology. It is also cultural. This shapes and, sadly, warps their so-called "Biblical" teachings.
Thus let us say they believe in the Bible teaching of the Golden Rule: "Do unto others as you would have them to do unto you." I believe that. But do I believe it the same way a JW does?
Jehovah's Witnesses might say they believe in the Golden Rule, but I posit that they do not.
They often do not view "others" as worthy of the Golden Rule at all times. They are often suspicious, even of members of their own religion.
First they automatically cancel-out all non-Witnesses as demonized outsiders, so they would not really "do unto them." And often, they would "mark" members in their own congregation. If someone did something they thought "smacked" of "demonic" activity or was just "bad association," a Witness would not "do unto them." And they would not "do unto" anyone in their own family who was "removed" (the "new" term for disfellowshipped), even though this person was their own blood.
A rabbi I knew once taught that it is not what one claims as creed to be their true beliefs but their actions, especially when they believe no one to be watching. What a person does then, that is their true creed, what they truly believe in. If a person publicly says they do not believe in watching porn, but they watch porn in secret--then they really believe in watching porn.
So you cannot really say you agree with anything the Witnesses teach or claim to believe. Their view of things is warped. Even when they claim they believe in the "Bible"--the "Bible" they believe in is a warped translation. So you cannot say you believe what they believe--unless you are still one of them.
