Words that incite one to hate go against my grain, and in a subtle way, I do think the Witnesses practice it. What, saying that 99% of mankind is not worthy of God's love and condemned to die isn't just a little hateful?
They're not squeamish one bit about the thought of Jehovah killing billions of children, whose only "crime" is being born of non Witness parents who don't indoctrinate their children in "the truth".
They're not one bit squeamish about saying that homosexuals, married people who practice "unnatural" sex acts, teenagers who through ignorance and peer pressure get pregnant, horny teenagers who can't keep it in their pants after watching Twilight, women wearing skimpy clothes, people who go to Vegas and leave it there, guys who wack off to porn, voters, people whose lives are saved with a blood transfusion, Wiccans, Pagans, Jews, Catholics, Baptists, Muslims, Buddhists etc. the list goes on and on, deserve to DIE categorically horribly at the hand of the God who claims to love humankind and created it IN love.
Whether you believe that or not about God, that's pretty strong and hateful speech. They're smart enough to stop short of inciting actual violence among their members, but the God they worship is one cold blooded serial killer, isn't he?
But, hate is like a terminal social disease...one person catches it, and everyone they have "intercourse" with catches it too. Stopping that is just as vital as stopping any other fatal disease before it kills.
