I find obscene language very unprofessional, so I guess it fits the bill either way.

Oh, c'mon... "We Are Morons"...

It is sort of funny for me to hear you offer the idea that "obscenity is OK because it is adults talking to adults" (paraphrasing you), since that is one argument I think is particularly apropos to opposing obscene language.

You're indeed paraphrasing him, because that's not what he is suggesting. The claim is, fundamentally, that that particular verb (as of itself) is not obscene at all, let alone the idea of sexual intercourse. And i wholeheartedly agree with him. There are by far more obscene things. Of course, we simply do not and probably cannot agree on this, and going on would probably spawn an endless discussion. So this is my last take on it, and it's just to explain that for the exact same reasons as explained by those who voted to keep the "incriminated" node, or would have done so, I would have as well, notwithstanding the fact that I do consider that attempt at humour to be particular poor, which is the reason why I did downvote it.
