I have confirming experiences too.
Sure some guys get weird about gender, but I DEFinitely think it’s a high skill vs low skill issue. Low skill players can be more emotional, overreactive, negative. They’re insecure about their play and might resort to talking shit. High skill players tend to be calm, cool, collected. They don’t have to talk shit bc their play backs them up. In team games, they’d recognize the importance of keeping the harmony in order to win.
