My friend: Homosexual people are disgusting. They should understand that love can exist only between a man and a woman.
Me: Do you love your boyfriend?
My friend: Of course! I love him so much. You can't even imagine. I've never been so in love in my life. I want to marry him.
Me: Imagine now that your boyfriend's penis disappears and suddenly he has a vagina. Nothing else changes in him, he's still the same person you know. What is your reaction?
My friend: That would be horrible. I don't want to even think about it. I couldn't imagine being with him.
Me: That means you don't love him. You love only his dick. That's sad.
