Gender when gender isn't an issue

When it comes to things that have nothing to do with physical ability, do you think that there should be teams for the separate genders? I don't find it necessary to have two separate teams. I was reading online just surfing the web, and i come across an ad for a Girls engineering team. What is the purpose of this? Wouldn't it make sense if there was just one team for something such has this? I assume that they would want more women to be interested in engineering, but you can easily do that but making an ad with a female engineer working in action, or something of the sort maybe with a team or even just posing, however making a separate team for just women seems a bit ridiculous. Sometimes i feel as if the 21st century is like a YouTube video, The advertisement loads perfectly and yet the video itself is buffering ever couple of seconds; time to wake up people.
