Sorry if it wasn't perfectly clear: I didn't say that it was victim blaming, just that it is problematic in a way that is not much different from victim blaming. So defending the suggestion as not victim blaming is kind of not great in my book.
It's always worth considering that "she should sue" is actually meant as "she has a clear right to sue, and I would applaud her receiving an appropriate amount of compensation should she do so, because that was completely unacceptable".
I tend to frame the sentiment as "That's lawsuit worthy and if she desires to bring one I wish her good luck and good hunting" for clarity, but I find that often people use "should" conversationally to mean "thing I would love to see happen" rather than "thing I believe the object of the sentence is required to do".
Yeah, I am aware of all that. I appreciate you making an effort to make a clearer distinction -- "that's lawsuit-worthy -- but I am less thrilled with having it explained to me that it is on the victim (or sympathetic women, like myself) to be emotionally sensitive to the intent of random internet strangers sloppily using "should" instead of being backed up on the idea that a predominantly male discussion group really ought to be making more of an effort to frame things carefully when they discuss what some woman has endured at the hands of other men.
