I remember when this topic came up years ago, although I didn't post, and the consensus swung very much the other way. I think it's kind of a different question now though, since so much of the NIN material released in the last half-decade is instrumentals and songs with no overtly objectionable content-- doesn't HM only have one song that contains a swear word? I think it was a lot easier to have a gut reaction of "No way!" when With_Teeth was the most recent album released.
I hope I can have kids some time over the next few years, and I honestly don't know what tack to take with this. I have no issue with the poppier NIN songs like EDIETS, but songs with dark themes and cursing I would probably skip, just to keep the kid from parroting back the lyrics. I realize there's a whole deeper debate about whether exposing kids to dark themes at a young age, with proper explanation, is actually more helpful to their development than shielding them from it (or whether vapid, bubblegum pop is actually more insidiously harmful to impressionable children in a different way) but I'm not addressing that right now-- I just wouldn't want the kid singing Closer in the supermarket ^^;;
