Conservative leaders and strong Christians such as the Palins do draw some intense hatred, even the Palin children draw some of the troll hatred.
I don’t know if it is the Christianity, or the conservatism, or being female that attracts the Palin haters, perhaps the combination of all three is just too much for some.
And good hates evil. "Hate what is evil; cling to what is good." Romans 12:9
