Why do people hate jehovah's witness,even though they follow bible
standards in everything they do?

I don't hate Jehovah's Witnesses. I don't agree with many of their
interpretations of the Bible, but I certainly don't hate them. I have
known some fine people who were JWs.

The people who dislike them probably just don't like having strangers
ring the doorbell. Some folks do not like to be disturbed.

It should be noted that not all door-to-door witnessing is done by
JWs. The Church of Jesus Christ of Latter-Day Saints ("Mormons") and
the Unification Church ("Moonies") are famously active in this kind of
outreach, too. I think the folks who are annoyed by Jehovah's
Witnesses sometimes lump all these missionaries together, as if they
are all the same, which probably vexes all three groups.
