Complaining about the little things can hurt the bigger cause if you piss people off in the process.
But if you start looking with fresh eyes you start to see again and again and again small things, apparently insignificant things, that all combine to say "Women aren't welcome here." This is a single, simple, tiny, apparently insignificant example, but it's utterly ubiquitous.
Your dismissal just makes it clear that you either haven't noticed, or don't care. It's a sobering thing to realise that there is just so much subliminal repelling of women from fields such as finance, programming, physics, mathematics, engineering, and more.

And it's horrifying. I always feel guilty that when I get tired of the fight I can give up for a while. But that's because I'm a cis-het white male, and the system is biased in my favour. Others can't choose to give up - and it's relentless.
