Choose mentors who will help you become the best official you can be - regardless of race or gender...I am a white male and have 6 people I would consider my mentors: 2 are other white males, two are women, and two are African-American (one woman and one male)... heck, one of the white males is Canandian - so he's a foreigner!
I chose each of them and approached them with the request to be my mentor based on their abilities, knowledge, and experience - not their race or gender...I can't honestly say I understand the positions of Juulie or Rut because I am not a woman or African-American, so haven't been in their shoes - but as an overall statement - choose mentors who will make you be better - don't limit yourself to race or gender issues...
