The article points out that girls have learned to be really competitive with each other while they are trying to make their way in a male-dominated world, but this often does not help them in life. "Camps like Rosie's Girls are truly refreshing in an age when the idea of women's spaces get constantly challenged by people who don't understand just how prevalent misogyny and patriarchy still are in our society. And by reaching young girls at such a critical stage in their development, they can navigate through life with that much more courage and strength — just like their feminist predecessors."
The specific camp mentioned in the article is only in California, Ohio, Rhode Island, New York, and Vermont, but it sounds like it is led by an organization that has a whole lot more than just summer camps to help girls and women with nontraditional careers.
I really do believe that this girls in STEM movement is gaining momentum across the country. I recently saw in my neighborhood newsletter that a Lansing, Michigan organization is putting on summer camps for girls with programming, design, and engineering activities taught by female instructors. They are not prohibitively expensive for families with low incomes, either, in order to make the opportunity accessible to all girls (only $25).
