I think that comes with the techy side of lemmy. IT is still very much a male-dominated field and while it's better now than it was maybe 10 years ago, the mentality lingers and women in tech still run into a lot of misogyny. It makes sense that more tech minded users who tend to work in or have a big interest in IT have that mentality.

Even posting this, I'm a bit hesitant. To be clear, Lemmy is significantly less awful in terms of a lot of things, but I agree that I have seen some loud voices when it comes to misogyny.
