Do men or women sing more karoake?

I got very definite, and very contrasting, answers to this question. Below are some of the variants.

(Excerpt from interview with Michelle Maga)

Melaena: Have you ever noticed—sorry, just keeping an eye on the tape—if there’s more men than women singing, or more women than men?

Michelle: Oh, usually more women.

Melaena: Why do you think that is?

Michelle: Because women are more social creatures. I think that has the biggest thing to do with it. Women aren’t as afraid to lay it on the line as men are, when it comes to their pride. It takes a lot of a certain kind of courage to get up there and look like a fool. Because that’s your biggest fear, is you’re going to get up there and you’re going to blow it and you’re going to look like a few.
