This note over at PassiveAggressiveNotes is a bit old, but it was new to me. A girl decides that, now that she is a full-blown vegan, her roommate is no longer allowed to bring food into the apartment they share together. She even compares eating meat to sexually abusing a child. She deserves to get slapped in the face with a pound of raw bacon.
To liberals, morality is determined by how much they think they are self-sacrifice they participate in, and therefore think you should be self-sacrificial too. They have zero tolerance for any other beliefs, but expect you to tolerate their idiotic worldviews.
