The viera are born from trees so that's why there aren't any males and I don't think they can reproduce, so maybe they aren't actually considered females? I don't think they all look like hookers. Fran does and the ones in the opening FMvs do, but most of the others don't and the amazon ladies don't look like strippers. They might not wear much, but their grass skirts doesn't exactly refer to whorism. I wish there were real life Viera strippers though. Just rubbing on those furry ears...
