This has been a topic very discussed, because there are many different opinions. On the one hand it is true that men have more strength that women, and are faster than them. So if the women play in a men´s team probably they will be hurt and it will be disadvantages for the team.
On the other hand, we know that there are exceptions, there are woman that can be faster and stronger than men but it’s a minority. I think that maybe in some sports we can include women and men, and they can help in the team, the men can bring the strength and the women the intelligence to make better strategies or something like that.
But in real life there aren’t too many sports in where women cannot be hurt by men, so in conclusion I think that women have to be separate with the men in the teams.
