I don't have any strong views about this. I'd just say each athlete must be assessed on an individual basis. There are some women who are already as powerful as men, some of the Russians I've seen at the Olympics for example. Many women tennis players are far more powerful than others; Martina was extremely powerful and the Williams sisters even more so.
So, just as in boxing a featherweight wouldn't be pitted against a heavyweight, the "new girls" should be in a category with those of similar weight and strength.
Also what splashcuba said.
I understand what Trent is saying about getting a load of unwanted emails after opening a link or signing a petition. It is a real pain, something I try to avoid as far as possible. I've only ever signed one online petition, would be reluctant to do it again. Still I get some really odd emails, I just block them.
