well I doubt many will agree that a tongue in cheek comment about a completely nonexistant person (find a fascist guerilla girl somewhere in the world likely to have sex with me) is on the level of threatening your opponent's sister or sexual harrassing a 4 year old.
I don't believe the opponent had a sister so that would make that personal nonexistant. If I'm wrong, I apologize. I also don't condone the comment made by Naso but just as you're able to justify your comments by claiming the person is nonexistant than the same argument could be used here.
Also, a threat of force is still inappropriate on the forum.
If you are talking about me, yes, I have a sister.
