"don't really need statistics, do they?"

I know plenty of women who would have no problem with any of the above. These things happen at some startups, don't happen at others, some women wouldn't want a workplace like this, others would enjoy it. And this is just one of many, many factors. Again, without more information you can't really say anything intelligent.

If your definition of "sexism" is something that all women would have a problem with, then by your definition there's no such thing as sexism anyway.

I know plenty of women that look at porn, one female friend continually makes jokes about raping me, and if you don't think that women talk about men when they're not around...

Not that I totally disagree with you, and most of my peer group is under 30. Just saying.

Note: I'm talking about in professional settings.

p.s.: watch out for your friend. ;)

While you're right that this isn't in a professional setting, I've also seen plenty of shenanigans on the job, too... admittedly, this has a lot to do with the individuals and the culture.
