Play the troll card

When one user questions or attacks another user, and the 2nd instantly accuses them of being a "troll". Often the first resort of those on shaky ground.

PD: "I don't think Asians should date Blacks."

Goldwing: "That's because you're a dumb racist."

PD: "Troll alert!"

Count X: "Man, don't even play the troll card, you racist shitbag."
