Why do males complain about female-led stories or too many female characters when the majority are still dominated by males?
One Woman in the Justice League
Just one woman, maybe two, in a team or group of men.

The Avengers:
In Marvel Comics:
"Labeled "Earth's Mightiest Heroes," the original Avengers consisted of Iron Man, Ant-Man, Hulk, Thor and the Wasp. Captain America was discovered trapped in ice in The Avengers issue #4, and joined the group after they revived him."
5 / 6 original members are male. Only one is female.
Modern films (MCU):
The original 6 Avengers were Iron Man, Captain America, Thor, Hulk, Hawkeye, and Black Widow.
Again, 5 / 6 original members are male. Only one is female.
Justice League
In DC comics:
"The Justice League originally consisted of Superman, Batman, Wonder Woman, Flash, Green Lantern, Martian Manhunter, and Aquaman"
6 / 7 original members are male. Only one is female.
In modern films (DCEU):
The members were/are Superman, Batman, Wonder Woman, Aquaman, Flash, Cyborg. (+ introducing Martian Manhunter (in Zack Snyder's Justice League director's cut))
5 / 6 main members in both versions of the Justice League film are male, with appearances by a 7th member in the director's cut who is also male. Only one member is female.
The Umbrella Academy (comics and show)
7 members:
Luther (Number One / Spaceboy)
Diego (Number Two / The Kraken)
Allison (Number Three / The Rumor)
Klaus (Number Four / The Séance)
Five (Number Five / The Boy)
Ben (Number Six / The Horror)
Vanya (Number Seven / The White Violin)
Later becomes known as Viktor and nonbinary in the television adaptation after Elliot Page's transition but that's not really relevant to this.
Here, 5 / 7 original members are male. Only two are female. Only slightly better than the other more famous superhero teams, and they had to add another member (compared to Avengers' 6 members) to improve the ratio (maybe executives still demanded to have 5 males).
Now let's look at some sitcoms and other stories.
It's Always Sunny in Philadelphia:
4 males, and 1 female slightly less prominent character who is abused constantly. The show claims to be politically aware and satirical but gets away with a lot of misogynistic comedy, tbh, that I'm willing to bet a lot of people are finding funny for the wrong reasons.
Community:
Jeff, Britta, Abed, Troy, Annie, Pierce, Shirley.
This one is a little better, 3/7 are female. Notice it's always more males though, they never let it become more than 50% female, or else then it's a "chick flick" or a "female team up" or "gender flipped" story. And of course the main character, and the leading few characters, are almost always male or mostly male.
Stranger Things:
Main original group of kids consisted of:
Mike, Will, Dustin, Lucas, and El (Eleven). 1 original female member, who is comparable to an alien and even plays the role of E.T. in direct homage. When they added Max, I saw people complaining that although they liked her, there should be only one female member. 🤦
Why is it 'iconic' to have only one female in a group of males? Does that just mean it's the tradition, the way it's always been? Can't we change that? Is it so that all the men can have a chance with the one girl, or so the males can always dominate the discussion with their use of force and manliness? Or so that whenever the team saves the day, it's mostly a bunch of men doing it, but with 'a little help' from a female/a few females (at most), too!
It's so fucked up and disgusting to me I've realised. And men don't seem to care. I'm a male and this is really disturbing to me now that I've woken up to it. How do women feel about this? Am I overreacting?
Once female speaking time reaches 30% or more, males believe that the females are dominating the speaking time.
Female encroachment on what has traditionally been considered male spaces is not taken well. Female empowerment is considered taking from deserving males.
Essentially the general male population don't like females, and only tolerate them as a subservient subclass who should be seen and not heard.
And it may also explain why people complain that there should only ever be one female character - it minimises the chances of males having to watch two females interact, because that would be excluding the male experience and they couldn't possibly relate to two females interacting.
EDIT2: comments in that video do claim there are more scenes... whether or not that really adds much is up to you.

The problem is that in the context of a "winner-take-all" society it does do that though.
Obviously the general solution is to make a society that is overall more equitable between those who succeed & those who don't.
But if you aren't going to do that then you will get a reaction from those who are losing ground, even if that happening is the morally progressive outcome.
