It's not Japanese culture. I know a fair few Japanese friends who are disgusted by lolicon.
The fact is, if you're drawing childlike characters and putting them in sexual situations.. there's something fucked there. Sure, they're not real, but it's still fucked up to be attracted to that in the first place. They look like children!
Mm.. it's a bit different. I'm a female game dev working in one of my country's bigger studios, and I'm one of two women who touches code (aka, software engineer/developer). Out of the whole company of ~300 people, there are only ~50 women. Most of those are artists, designers, QA, production, audio, HR , or other higher ups in the company.
It's no secret that they're desperately trying to get more female engineers on board, but there's just a huge shortage of tech talent where I live, and a lot of women are driven off from game dev because of the reactions and treatment that are so typical of the environment. Even getting here, everything has been very male-dominated through my entire career; women in tech just aren't as common for countless reasons.
I'd love to see statistics for some of the really big companies, actually.
