Let's call them women. Women who are, intentionally or not, in a pretty bad place right now. They're not enjoying this, any more than the accused men are.
Are they opportunists? Some of them probably are (looking especially at Nauright (sp?) for this one). But probably not all of them.
Are they prostitutes? We've seen nothing that indicates any of them are.
Are they "loose" or "sluts" or any other, similar derogatory nouns or adjectives (including the one you chose to use)? We simply don't know. Chances are, maybe so for some of them, and probably not for most.
So of all those choice words, the only one that seems to fit 100% of them is "women." So why not just call them women?
My personal guess is, there are a lot of victims in this sweeping money grab, both male and female, individuals and institutions, and only the plaintiffs' lawyer sees nothing but up side.
