As our good friend Naedell Blackrock shows, violence is always taken seriously!
That's who I thought of also!
In Cantr, it doesn't seem to be harder to be taken seriously as a female. I guess unless you act as a stereotypical girly type, but in that case, you get an extreme amount of attention, from what I've seen.
Not including my first two characters who died from not knowing how to play, I created 7 female characters and 8 male characters early on. Afterwards I decided to no longer create female characters. However, only two have died (and one was saved from death twice before dying) In the mean time, 12 out of 20 male characters died. Each of my female characters are relatively successful and are taken seriously (except for my Spanish characters). Only two of my old male characters are still alive. I can think of cases where I probably would have died if not a female and wouldn't have if I was one.
Still, I'm male, so I don't think it would be right to make more female characters. Just the idea of a new one seems weird to me. Being old gives my female characters an excuse for acting the way they do.
