Every church I've attended after leaving, I've never heard anything negative spoken about any group, much less JWs. There seems a conscious effort to be tolerant and respectful of other denominations and religions. It is quite different than services at the Kingdom Hall, which is tantamount to hate speech in regard "Christendom" or other religions.
Many churchgoers consider JWs "nice people", not realizing the danger the organization poses. Nor do people seem to want to know.
