Yes, it is to me. English (and most languages tbh) has constructs that constantly reinforce a concept of binary genders and highlight that as an important factor.

When you learned about Mr., Miss, and Mrs. did you find that awkward? To know how to title a woman (absent the more modern Ms.) you'd need to know their marital status - but for dudes it's whatever? That fucking pissed me off as a kid - how are you supposed to know if someone is married when writing them and who fucking cares...

To me, at least, gendered pronouns are the same way - I'm writing to a person, about a thing, as them as an individual. Gender is generally irrelevant to this interaction so why the fuck is it necessary for it.

Imagine if it was astrology sign instead: I just finished writing up a response to OsrsNeedsF2P. I hope Virgo appreciates the care I put into it because I enjoy the question Virgo asked.

Imagine needing to know someone's birth sign to talk about them and imagine that English constantly reinforced that birth sign was the way to identify others and that there were twelve and only twelve proper birth signs.

Gender expression is an important part of our identities - I have a complex expression as a non-conforming man - but it's not the important part of our identity. It's a factor of our identity and, I'd argue, only really rarely a top five factor. People are philosophers, crafters, writers, artists, hikers, gamers, cooks, painters, etc... those activities we enjoy are much more core to most of our identities. Our gender expression is important but should usually only impact a very narrow portion of our identity.

So to me, yea, it's a real issue.
