So on the topic of gay characters in media, which I know, I'm slow to as usual, I'm fine with either portrayal. I'm fine with it being subtle or as noticeable and flamboyant as a rainbow.
The subtle types are the most common though, definitely. Heck, closet ones are probably the most common, by far. I've never had a guy who's been in love with me that's openly gay besides my current boyfriend, of course.(Even then he can't IRL because, well, being in the middle of the swamps of Louisiana by two fundamentalists.) All of them identified as straight to everyone else.
But on the other hand, the very open ones do exist. Such as I.
Well when I said "a focus of the character", I don't mean "they're super flamboyant and talk like thiiiissssssssss". Hell, I don't even consider that on it's own to be actually addressing homosexuality as a theme.
You guys are reading what I say and twisting it into a black and white, extreme sense.
My initial point was that when it's a kid show, if you are gonna have gay characters at all, use them to convey a message.
Having characters that are gay for no reason in a kids show doesn't work because they aren't making an impact. They may as well not be gay and not progress is made, because kids understand nothing new.
However, if you make it a legitimate theme and convey the struggles of being gay, and then end that struggle in a positive way, you have a much more impactful and successful situation.
For example, let's pretend you have a show set in high school or whatever. You want to have one of the teenagers among the main cast be gay, because you want to positively represent that character trait.
You could, for example:
A) Have it be randomly brought up once or twice with no real focus.
B) Have the character be the stereotypical, flamboyant gay and constantly use them for jokes.
C) Have it not even be apparent that they are gay for a while, but in the middle of the series, start a short arc where they come out as gay, go through some struggles regarding that (such as bullying, anxiety, etc), get support from their friends and family, and in the end, are able to comfortably keep going with their sexuality and it makes no difference to the time they spend with their friends. Maybe they even find someone else who is the same as them. Or they simply resolve to knuckle down on their studies and not worry about finding a lover until they finish school.
Option A just means kids will not even notice and so they learn nothing.
Option B just means kids might not take gay people seriously and might lead to more bigotry from our youth.
Option C means kids should be able to empathise with the idea of being gay and what that can mean for someone, since they just saw a character they previously loved regardless of their sexuality, go through this struggle with it, and come out on top.
This really goes for anything, not just the issue of homosexuality. It's the same if you wanted to, for example, introduce a character with deceased loved ones, in a kids show.
There is also Option D, which is basically Option C, except the entire show instead of just an arc within a show. That can work too and create a very meaningful narrative, but can also alienate kids if it's the selling point since they may not get it.
