I think it is the use of the word "fraternal". It means "of or like a brother or brothers", implying male gender.

"be relaxed and relax them too, with a fraternal and understanding tone"

The word "friendly" would have been a simpler synonym in that sentence.

In Star-Trek, "Sir" is gender-neutral.
