I don't know, i'm glad I don't have to train with people like that. If your dog can't be around a female in heat, it isn't trained, and you better work on that. If dogs are competing, they better be able to compete around and intact and in heat female. If you're holding training classes, you better be able to teach your students that these things come up and really aren't all the difficult to deal with and train thru, so do it. The whole "in heat" things that people make excuses for and against drive me nuts too. Shut up and train, it really isn't that big of deal.
