Have you ever had a conversation that went like this?
You: When you did this, that, and the other thing, it hurt me in these ways. I am upset at you for hurting me, and afraid that you'll hurt me again.
Them: *sobs* How can you say such mean things? ; ;
You may not have known it, but your conversational partner was equipped with the Narc-Filter 2000™! A patented invention by Narcissists, Inc., the Narc-Filter 2000™ turns intelligible thought:
You: When you did this, it hurt me.
... into hateful, meaningless gibberish!
You: RARGHLE BLARGLE BLAH! FUCK YOU!!!1!
This not only lets you keep on doing thoughtless deeds, saying bigoted words, and being an all-around asshole. It also helps you feel good about doing it! You'll love it when the community rallies around you, shares in your misery, and feeds you that sweet N-supply. Just tell them how mean that uppity *CENSOR BLEEP* was to you, and then drink it all in through your crocodile tears.
