Well, "[Average Americans think that if a woman complains of a rape in some form, then] she probably deserved it, or is a weakling, or some other strong negative affect.""

I read that as that people make a negative judgement, of which be deserving or being a weakling is among them not uncommonly and is typical of the category in general.

If you wanted to demonstrate that the "deserved it" judgement was an outlier, I would expect some modifier or formulation like "[they consider...] that she's overplaying it, or some other negative effect, even seemingly that she deserved it somehow."

Unless you were trying to invoke this trope:
