Be proactive

If you notice bias you can, and should, take steps to counter it.

For example, in the context of bias against women, you can organise some female only bands. I have done so and it has prompted women to conduct and/or ring something that they would not usually get the chance to ring. I had comments about the different feel in the room (in a positive way) when ringing with an all-female band. And I have had women say they were trying something they wouldn't be prepared to try in front of some of our strong male ringers.

I love ringing with good ringers, male or female. It seems that some positive discrimination might help develop more strong ringers and conductors which will benefit everyone.
