If you can't train with every single person at our dojo you need to find another dojo. And you can give out your any kind of flyers somewhere else.
I knew a teacher who was confronted by a young lady who insisted that she would not train with men and it was her right to impose her needs on a working dojo. I wont go into the background of her beliefs but his answer was brilliant. He said he was happy to teach her Aikido but she had to arrange a sizable enough group to make it work out. He doubled his income and student base.
