I'm not speaking about male characters simply getting less screentime, I'm speaking about them being underutilized compared to their female counterparts, and used simply to prop them up, rather than just...idk, writing decent male characters along with female characters that don't need to be lazily 'propped up'. =/ In a nutshell.
This is kinda what I was actually talking about in the OP...no one pays attention to the subtle issues within the observation, all they see is "girl power!" and react accordingly. Misogynists whine about female characters getting "too much" spotlight; others just see it as "fair" compared to male-dominated media of the past.
Two points:
A) I really hate to think of things 'balancing out' in that way...bad writing is bad writing; doesn't matter how many barriers are being "broken down". Just because I want to see more female characters doesn't mean I ALSO want to see male characters being treated like dirt. Hot take, but gender isn't the first thing I think about when I fall in love with a character and become invested in their story.
The fact that a character of an overrepresented demographic is written like a garbage can doesn't make me feel like justice is being done...and the sad part is that oftentimes it happens because writers feel like that alone constitutes "justice". T_T Nice try, but no. It takes a little more effort than that.
B) The fact that, as I said, the whole issue is subtly misogynistic, is what makes it niche and unique in the modern media landscape. It's a very specific species of "girl power!" writing that actually just drags down the whole cast: female characters get the bare minimum of creative effort, and male characters get none, in order to make the female characters look better. No one wins.
I really can't get into a debate about RWBY here (no matter how much I might like to...); it would take way too much time and go way off topic. ^^; Let it be said though that I've thought extensively about all the points you've brought up, and I've seen other people do the same for years...without realizing that they're just looking at the surface.
A lot of the male side characters pull their weight, definitely, but look at how the narrative treats them for it. Are their successes emphasized, or simply brushed aside? When they go through rough patches, are they supported or berated? Do their character arcs actually reach conclusions, or just fall apart somewhere along the way? Are their opinions valued? Are their skills and insights utilized to their full potential, or anywhere close...?
Also, about Salem: her story isn't anywhere near over (especially considering how little they've used her since she actually encountered the cast...); and she's been shown to be evil, yes, but not explicitly irredeemable. Honestly, the fact that her curse hinges on her literally learning a lesson suggests the opposite. =/
