First of all she is only an alleged victim. Neither the university nor police found evidence to conclude that she had probably been raped.It is a disparaging label applied to a rape victim. Is it really that difficult?
As to disparaging, I disagree. It merely describes what she is doing.
Pull the other one. That one's tired. You meant it as a sarcastic insult and no one would mistake it for anything else. Since she is not a member of this forum, you are free to apply any label you wish. Although we do place restrictions on labels applied to one another around here, there is no way to prevent anyone from demonstrating their deficiencies. You have made yourself plain.
