First off. Emil is in the game because one of the team members is a trans man and I wanted to have more than one single kind of rep in the game. It also allowed me to reference the FTM Bois Bar in Shinjuku, a real life event
Second, I don't mind male characters in lesbian stories or stories aimed at girls, I mind men taking over the narrative in a heteronormative fashion. Whatever you're suggesting here is projection. Hell, most of the GL manga I recommend have men in them to some extent, they're just not the main focus.
I'm guessing my "rants" reference things like me complaining about Pripara having a male unit now, which I've pointed out several times is a problem to me because of how they've been used to steer the narrative towards "girls like boys", not because boys exist. Hell, the series had men before that and I never had a problem with that aspect for a good three years of the series.
I've said it plenty of times, I don't much care for stories revolving around men or heterosexual romance stories. It's not hypocritical of me to have a male supporting character regardless if he's cis or straight, which in this case, Emil isn't.
So no, to close this out. I don't believe you can't have men in a Girls Love story. I'm just not interested in anything focusing on them. If I couldn't like GL with boys in it I would never be able to like Their Story or After Hours, for example. Both of which I love.
