In this study, when women were faced with the same condescending explanation, voice nonrecognition, or interruption from a male or female co-worker, the women reacted more negatively and were more likely to see the behavior as indicating gender bias when the co-worker was male.

Another female journalist trying to maybe kinda sorta possibly want to try to understand and empathise with boys and men. But she can't quite get there. She repeatedly dips her toe in for a nanosecond before quickly retreating to same something about girls and women.
