This is a little different for me.
I have always been a not sure about cheer-leading. My view is that girls and women are better off as participants in the game, not cheer-leading the boys. But cheer-leading is a big thing in the USA and increasingly world wide. And I can see it as a sport in its own right. The women here are scientists, engineers and science communicators; cheer-leading is passion. And they have every right to encourage girls into science.
