Watchtower wishes it could achieve what LDS has achieved- whacky cult accepted into the mainstream, tithing, and members who are rich and in politics.
A cult is a cult is a cult. Many similarities. I could compare them to Scientology and many things would be similar, mostly having to do with ex-members and having to reach higher levels to learn other secrets of the cult.
But each has their particular strain of whackof- with Watchtower it's Armageddon around the next corner, blood transfusions, keeping out of the military and politics.
