Your grandparents' grandparents knew Clown. He is an ancient entity who has survived many historical events. He was the demonic figure they flocked to during the Salem Witch Trials, and their love for Clown got them hanged from the gallows. Love for Clown is destruction for the human race. That is why they decided to hate him instead. It was always the safer option.
