As I have stated previously on other threads about this, there really are only two ways to interpret this action by WN.
Either they're going back on their word and mis-using the term "female lead" after they've already agreed not to due to user backlash, or they're calling gay males "female", which is so much worse.
So at best, they're incompetent. At worst, they're wildly ignorant, sexist, and homophobic. But hey, good luck getting Webnovel to actually respond to this concern on their shithole of a website.
