I hope that's not the case for many, though there are definitely a few out there who get hung up on this. And if I had to guess it's also partly because one male option leaves so much to be desired that everything else seems 'better'. While there may be a link between more female options and slight objectification that can be used to explain the different amounts of same-sex options (though I do believe it would take analysis of the dialogue rather than just looking at quantity), I feel that this argument is often lost in favor of a "they have more and that's bad" - type argument.
For me, the point has never been a numbers game in the sense of one gender having more than another. That argument just strikes me as irrelevant. I want more than one person to romance, and preferably, I'd like the whole cast to be available. I don't think it's bad to make the dialogues similar regardless of gender, nor is it much more work. (Though more than anything I just want Ashe ❤️ ).
