My top 3:
- There is no honourable way to leave once baptised
- They frequently accuse other religions of what they themselves are guilty of
- Their claim to be "publishers of the Good News" or evangelisers is false. They are "publishers of religion" or proselytisers.
(Why do followers of the Watchtower religion call themselves “publishers of the Good News” whilst unfamiliar with the “Good News” according to Paul, Moses, Isaiah and Psalms?)
