I asked my only female coworker about this, and she said she had never experienced sexual harassment, and found tech culture tame compared with finance, where people would shout at programmers over the phone if things went wrong.
Ugh - yes, ignore my comment. I misread your intent completely.
FWIW, I know someone who takes a very public stand online with a few feminist issues and she cops brutal reactions on the net. I think many people simply cannot contain their natural reaction to beat down someone (especially a woman) who they perceive as being successful, or not deserving success by some metric (beauty, body, etc) unrelated to the point.
You do realize that finance is one of the worst places for representation of women and is recognized as a cesspit? (http://www.forbes.com/forbes/2009/0316/072_terminated_women....). It's wonderful that your friend has had positive experiences throughout her career.
She never said finance was sexist, only that people were rude in general. I'm not making any claims myself, only relating the experience of a colleague.
Just one data point.
