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.
But I'm also not going to correct someone who doesn't use singular they (unless it's in a situation where they should be following a particular style guide that specifies it).
English is not my mother tongue, and I actually thought here I was being sensitive, cause putting "he" would have implied only males are career oriented, etc. Didn't occur to me I could have put they.
