If somebody had a "fuck you" bumper sticker, would you smash their taillight? Even if you're a technically sophisticated asshole, you're still an asshole...
But how do you know the intent of the other people around you? Maybe they're just making a joke. I think iloveanal sounds kind of funny. Do you ask them before conducting your deauth attack?
I'm talking specifically about people who name their networks things like "Anal Creampie Snowball" or "Gaping Asshole".
I'm not saying what you're doing should be /illegal/ just that you're being a gigantic prick by doing it, and that you're inviting me to be a gigantic prick back to you.
Getting offended at such a intense level over something that has no appreciable consequence is definitely an issue. It isn't like wifi network names are spray painted on the side of your house.
If you want to act like an inconsiderate 14 year old with your wifi, so will I!
