> but a woman would not be labelled a liability for reporting a rape or an assault, unless maybe it turned out to be false

This is the crux of the matter and where most men run into trouble with this whole discussion.

Let's say she comes forward and accuses a coworker of rape. The coworker denies the allegations and says she's lying to punish him for some work-related disagrement, or because he turned her down for a date or something. She doesn't have any recordings or physical proof. It's just her word against his.

Now what?? Well if you want to get a sense of what typically happens, take a look at this thread, in which multiple men are spending thousands of words debating the fine points of what exactly is bad enough to count as "rape", and why didn't she just quit, etc.

Basically: when there is not solid proof, guys tend to stick up for each other--and there are way way more guys in tech than women.

That's why she would fear being ostracized.
