So, it's okay for someone to say, "I won't help <race> <gender>, they can forget it", as long as <race>="white" and <gender>="male"?

And how do you define mentoring? Clubs? Participation in class?

Is an Italian man's participation in an open-source project equal to an American's? A Russian's? Why, because they're 'white'?

Should a Swedish man then be barred from help?

Anyone's time is their own to decide how to spend it.

You seem to be trying to portray some kind of malicious intent by someone who in real life is a very nice and humble guy.
