Having worked with designers in an ad agency (although not a designer myself), the male designers didn’t ever have a good thing to say about the work of any of the female designers. Consequently, none of them stuck around for long (one of them is a creative director in a big agency now, so presumably she wasn’t that bad).
Then again, they were assholes in many other respects as well, and the guys in the next companies I worked for were a lot better.
