At some point you have to stand up for this. Yes, it might cost you, but it is easy to punish companies for their behavior here. SV is still an exception, but I believe companies with such HR policies have a severe problem with drawing talent. While it might be nice to work with more women for once, such discrimination isn't worth it. People supporting this are terribly afraid of dirt and the best strategy is to turn the most ideological followers against them. That isn't as hard as you might believe as everybody will make mistakes at some point.
