There is absolutely hateful speech in Scripture
Jesus said that those who don't eat his flesh and drink his blood are dead with no life in them. John 6, That is bigotry.
The New Testament says repeatedly people will be thrown into the darkness where there will be wailing and gnashing of teeth and torment that lasts forever and ever. Those not written in the book of life will be thrown into a lake of fire. That is pure hatred because it is pure cruelty, and the epitome of cruelty. In my opinion, extreme forms of sadistic cruelty = hatred!
If your definition of "hate speech" and "bigotry" is preaching a truth and an eternal condemnation then I suppose you would say it is in the Scriptures.
