Most crimes of words or planning are like that:
* Conspiracy is only illegal because it is “conspiracy to commit <something illegal>”.
* Slander is a problem because of the potential for damage to one's business, and social standing.
* Intimidation of various kinds — including “assault” which is the threat of bodily harm — is problematic because it is so clearly tied to injury (or the disruption or destruction of one’s property, livelihood and so forth).
If we examine intimidation, it sheds light on harassment (and overt racism, homophobia and the like). One does not have to spell out the threat of bodily harm in precise detail for it to be assualt. Words and actions that constitute a credible threat are enough.
Not every homophobic comment, Nazi salute or joke about women constitutes a positive threat; but in many circumstances they do carry with them a threat: of loss of standing or esteem or even of one’s job.
It is not an individual remark like “I like your behind” that constitutes a problem in the work environment, but these cases are never an issue of an individual remark.
> If the harassment occurred in a language she didn’t understand...
This is a non sequitur. Does intimidation in another language count?
