You don't have to sterilise your languge; it just takes a little bit of practise. It's something of a myth that language must be sterilised to be inclusive. Perhaps see it as a challenge to your language skills rather than a prison sentence?
I did the same thing myself with my general assumption that all online authors are 'he' until otherwise noted, with the excuse that it eased the 'he/she' usage issue. That annoyed the living shit out of me, as it was really an excuse for laziness, so I changed it. Now you'll usually see me refer directly to someone's handle, an article author's surname* when it's known, or just say 'the author'. Occasionally it makes the sentence feel a touch stilted, so I haven't perfected it, but I'm much happier with that than the previous way. Sometimes I use 'they', which is gaining acceptance, but there's still a group of people that can't stand the singular 'they'. Overall it was fun training myself that way.
You'll be under more scrutiny, admittedly :)
*What prompted me to do this was watching a political talking heads show. I noticed that male politicians were always referred to by surname, as were older female ones, but young female politicians got the informal first-name treatment. It really drove home the difference in professional respect given to the various groups.
