Well, when I look at the list, these are the items that I found that prove that they are a cult, not that they aren't:
We keep coming to your doors even though we have regular jobs and family like you because we are admonished to do so by Jesus Christ.
There are currently over 300 Jehovah's witnesses in Prison in South Korea and Egypt because they refused to stop preaching or enlist in the military.
We don't salute the flag or say national Anthems because we pledge our allegiance only to God.
Yes we have fun and party too so don't get that twisted.
Not many of us know the name of the President of our headquarters because we do not pay any reference to him He is a fellow servant of God just like the rest of us are.
You earn the privilege of becoming a Jehovah's Witness. It's not given to you or passed down.
We sin too.
Do you know as a Jehovah's Witness I could visit China and spend a night at any Jehovah's Witnesses without either of us feeling suspicious of each other.
Last year Jehovah's witnesses around the World spent a total of 1,841,180,235 hours preaching .
That's not including the fact that they feel compelled to prove that they aren't a cult. The fact that they have to constantly explain and defend themselves is proof of that too.
I agree that none of the items in the list proof that the aren't a cultic organization. However, if you look at the larger picture, the list looks like a promotion of the WT than anything else. That post doesn't look like any invitation to conversation, nor an invitation to be questioned about their statements.
Also, based on what I know about cultic organizations and relationships, they are way off in making those statements that don't even remotely relate to the very definitions of cults and cultic relationships.
