As well as sharing their grievances about such examples of sexism, and in order to drive home their message that girls and boys are equal, the founders of Girls United shrewdly incorporated a “boy’s perspective” section onto the site.

“If people see it’s only girls on the site they will think we think girls are better than boys, or that if you are a feminist you think girls are better than boys – but that’s not true,” Ella explained. “Also, gender bias can affect boys as well, if they don’t fit into the mould of what a typical boy is supposed to be.”

The contributions to this part of the site, which have so far been written by Ella’s eight-year-old brother Logan, include examples of the sexism that boys can encounter at a young age. One of Logan’s stories is about the bathroom passes at his school, which he dislikes because the girls’ ones are pink and flowery while the boys’ ones are black and plain.

“Basically, it is saying girls are pretty and dainty, and telling them that they should be, and saying boys are funny, but plain and simple,” he wrote.

Speaking to stylist.co.uk, Logan said it was important for feminist websites to include a male point of view. “If they didn’t, boys wouldn’t be convinced that they can believe in this too,” he said.
