While I haven't seen many hard statistics on the matter, the cultural interpretation is definitely that SV has a hard time with women and minorities. Highly prominent examples in the news like Uber don't improve this image. Also the conversation around Google (regardless of your "stance") has been filled with vitriol lately.
While I'm still questioning where I stand amidst the Google stuff lately, it's pretty clear that there are some really screwed up people in this industry that legitimately think women can't do as well in this job (not saying Google was an example of this, it's just that story brought a lot of the roaches out from under the fridge).
Going by Google searches, it looks like the NYtimes has been writing a lot of stories about sexual harassment in SV. Some have been pretty click-baity opinion pieces, but overall I think their coverage has been quite good.
So my point is, this may not actually be a "pandemic" but SV is where this stuff is being talked about in context to. So it makes sense to frame the conversation as "Why is SV where all these stories are coming from anyways?"
(You could always just say that the "Fake Nytimes is just looking for clicks again" but I find that argument misses the forest for the trees.)
