Men and Women in sports - together or separately?

Normally in the world of sports, men and women play separately but there are sports where the teams are mixed.

On the one hand, most people think that men and women should be separated because men have a higher constitution or stronger than women.

Moreover, there are people who think is a discrimination can't play on the same machine men and women.

In my opinion, I think we are all alike and if there were mixed teams, we could all enjoy most sports and all could participate more in them.
