Thinkng about the AIBU thread where the system got confused because the OP was a Mrs but had kept her surname - so it kept asking for her maiden name.
Which systems out there must have been designed by a non feminist? I was going to say male but I think that would have been a bit sexist?
Have you noticed that when you have a drop down menu - it's predominantly Mr that comes first. Then all the female titles?
Little things, I know. I'm sure you can find some bigger things where the system is just not designed to cope with women.
