FOR GIRLS

Today I saw a commercial from Nintendo about them launching a "Nintendo Girls Club".
I frowned. I've had enough of this sexism against boys.

For some reason, everytime something is produced "for females", it includes the notion that men are not allowed to show their face, and truth is; if these kind of events and clubs were set up for men and they'd put the slogan "GIRLS NOT ALLOWED" on their signs, feminists would go apeshit.
I know there are enough instances where it's implied it's for men and females can't just jump in, like in most sports, but there's really no need to divide something that's neutral. Like video games.
Why is there a Nintendo club specifically for girls? Why does the media still think that putting a clear distinction between two kinds of people is an effective solution against sexism/discrimination?

Just stop for one minute. Stop talking about it. Stop pointing out who has the penis and who has the vagina, we know this already.

Girls do not need their own special little group where the wallpaper is pink.
