I must say that I do not care if I am sitting next to a Male or Female on the flight deck. As long as they are qualified and meet the standards that are required for the position.
If they do not meet these standards (male or female) then they should not be there.
I do get a little annoyed with companies that have a quota system and require a certain percentage of their pilots to be a specific gender. This is causing companies to lower their standards just to meet numbers, this should not happen.
