Yes I have mixed feelings on this too. To be equal and fair with the rulings on football and netball there would be separate men/mixed/female.
However, in cricket at the moment amongst teens, there aren’t enough good female players to run decent leagues in most places. In our club we have some fantastic female players (county level players) and they are part of the “boys” squad so they rotate into the “boys” team for matches, and get a pretty equal number of matches as the boys. If they were confined to just playing female teams they would get hardly any - if any - matches except when they play for the county. At this junior level they are better than some and equal to most of the boys. I accept that at county level and higher the strength etc of the boys means that single sex teams are appropriate.
It seems in this case therefore that girls/women would miss out. Unless the ECB allows mixed teams for competitive sub county matches. I honestly think this is what the female players would want. However, I do think that (some) of the boys would prefer to exclude the girls so they get more play themselves.
Once girls cricket is sufficiently mature, girls leagues will hopefully get established.
