uhhh...? Idk. That doesn't mean the higher skilled dudes are being kind to chicks. They were just being 'nice'.
They might have been 'nice' while not feeling threatened, OR they might have actually been chill with anyone of lower skill level.
I don't think the difference is "git gud and get better at inter-gender social interaction."
I think the difference is "feel secure and get better at non-hierarchical social interaction."
