You can’t rule out self selection at work. More women who like to lead (and follow) signing up because it was already advertised as a double role event. Or friendly to double tone. Simultaneously discouraging anyone who is single role person from wanting to attend.Hm. For being a double role event, I can only see two or three men following, and the majority of men are leading. I can't say I like the atmosphere either, it gives me a strange feeling, but I don't know if it's the dancers or the location that does it.
