Women are often unfairly stereotyped as being less-skilled or less-capable than their male counter-parts in our industry. Suggesting those that need help are female is just the thin-end of the wedge on this and may go unnoticed by those using it - a "micro-aggression" as it is now being called - but it furthers the entrenched stereotyping.
Using well-accepted gender neutral pronouns is a simple step to avoid this sort of thing and try and promote equality and diversity in our industry.
If I have offended anyone, sorry - that was not the intention. The intention was to promote gender equality and make our industry more welcoming to all genders.
