@Caelestie It would be contrived because they just said they couldn't fit more characters yet. Did you not read that? Of course it applies to other things, If you actually read what I said you would know I never said or implied that it's only contrived when you try to add female characters.
You really need to chill out and stop trying to nail shit on people when they are trying to communicate and may or may not use the correct words. And yes, it can be forced even when you have that "perfect ratio", because you are deliberately trying to go for that ratio. You can still have strong female characters, strong black characters and strong whatever else characters without making it forced. Just do not have them just to be politically correct, or add in those characters when they don't makes sense to appear.
I could be white, make a bunch of black characters and that would be forced, should they not be ethnically possible in my story.

Same thing goes for females or males, with any context if you try and add more than what you can reasonably add there or come up with, and no one should feel bad about only writing about what they know and are comfortable with.
@JigokuNeko I may not know much about specific research, but I do agree that girls get shafted. However, I don't agree that it gets problematic at all with the example you said. In that example, an all male cast with little female interaction or representation could be for either boys or girls. The only reason they might be known is because they are their girlfriend or mother, and it would make sense to include them because of specific story elements. Flip this around for girls after. In Sailor Moon, the only guys are for romance or fighting exclusively. Yes the cast ratio is contrived, but if you're going to appeal to a bunch of girls it's a valid way to do that and show them strong female leads. Fleshing them out may not even make sense, if the screen time should be spent on the main focus of the story. Thank you for being civilized though.
