I suggest that you don't opt out.

There is a lot of assumptions you have made about what the training will be about and the reason for it. It sounds like you don't have any problem with the concepts of being inclusive and trying to be aware of unconscious bias, but you think it isn't the big problem people make it out to be, and not something you need training in. But how do you know for sure unless you attend?

If you attend you can ask questions, give your contributions, and give feedback later on whether it was helpful or not. Maybe you will actually learn something new, maybe you won't, but having a closed mind about it won't benefit anyone.
