There's a need for gender neutral pronouns in our society.
I write this as someone who works in fields often dominated by females.
For example, I've decades of experience working in communications and it's common to be one of a handful of men when I attend conferences.
While working with the Murrumbidgee CMA I was in a communications team with three women. It was somewhat confronting when the general manager called his "media tarts" to the stage during a meeting of the entire organisation.
A couple of weeks ago I was the only male at a meeting and was surprised when the group was collectively addressed as "girls" -- but mostly because I similarly reject being addressed as a "boy" for the inherent infantalising in that term also.
While I'm not convinced that "comrade" is the best word to take forward, it is one of the options that seems to connote a sense that we are all equals.
