When my friends (Christian) talk to me about the Radical Left, I quote Jesus to them:
“Then he will say to those on his left, ‘Depart from me, you who are cursed, into the eternal fire prepared for the devil and his angels. For I was hungry and you gave me nothing to eat, I was thirsty and you gave me nothing to drink, I was a stranger and you did not invite me in, I needed clothes and you did not clothe me, I was sick and in prison and you did not look after me.’

So I remind them that, according to Jesus, THEY'RE the Radical Left. And they might as well admit their love for goats.
