You are right, cofty...the leaflet doesn't really qualify as "hate" literature.
It is just simply misleading. The JWs are guilty of spreading misleading information, that's all.
And, they aren't the only ones who think that homosexuality is "just a bad habit".
The Bible condemns a lot of behavior, such as wearing cloth made of differing fibers and silly things like that. But I don't see the JWs spreading literature around calling the wearing of mixed fibers a bad habit.
