I mean... I guess it's not a useless discussion and I'm not in a position to comment much as it seems a guys' problem overall.
As a lesbian I think the MC attitude towards yuri is more commendable than the other one. But both of them are creepy anyway.
Always curious of what guys feel about yuri tho. Especially about the yuris that are clearly targetted to women. If it was just about fetishizing homosexuality (...irk...) there wouldn't be so much activity on a lot of mangas I read.
What is the population ratio of this site by the way, gender-wise ?
It's not like there's a blanket description for why a category of people does something (I know you probably didn't mean to imply anything like that, just reminding) but Ch 4 does a pretty good job showing a couple of the reasons that can pull people in. But complicating things even further, these two guys had that talk in Ch 4, yet only realized in Ch 6 that the word "yuri" they discussed meant something completely different to each of them...
As for my input, I think in general, yuri tends to contain girls, so people who are a fan of girls will probably tend to be interested in it more often than people who aren't. Sort of like how yaoi tends to contain guys, so people who are a fan of guys... yadda yadda. And for what it's worth, both tend to contain humans, and be written by humans, so anyone interested in humans can probably appreciate works in each.
