From what Id read and heard about this story before, was that these guys were on a stag due, dressed up in drag, which for me, makes the story better and funnier, the fact that the drunk idiots, started on these trained fighters!
It would have been sad if they had started on genuine MtFs, its horrible to think of any poor woman being vicitimized.
And Im from the Midlands in the UK, and violent behaviour is very common in drunk people, both male and female!
