Are girls really more qualified ("physical attributes" as you said) to participate in gymnastics then males?? how so? don't give me flexibility reasons because that isn't true for any male gymnast.
I wouldn't really consider pool or table tennis to be a sport. bowling somewhat. Although I completely agree with you that these "sports" should not be gender specific.
I agree again with you that females should play with only females. However, if a female is truly capable of competing against a guy then why not? It is a KNOWN fact, whether anyone would like to admit it or not, but males ARE better than females at SPORTS. Therefore, if a female can compete with men then they should be given the opportunity. However, I have yet to see a female who can compete against males. (compete = on the same skill level as men and not just the physical act of competing)
