What has holding a door open got to do with sexism? Its a matter of attitude and culture I think. I've noticed that a lot of black guys like to dash through the door first and Chinese guys. I'm not sure if they are scared that they will appear weak if they let a woman go through first?
Black people walk in first so they can protect the woman behind him from anything harmful INSIDE or atleast that's what a black friend of mine told me.
, why you derailing this thread?
