it was pure jealousy on the part of the professional game.

because the men at war in WW1 - the women took up the challenge of entertaining (?) the public and it was virtually the only option around. Men returning needed a job and football was a good second income. Women had to look after the children. It was the culture then.

But yes, it was a form of jealousy - money.

And there were plenty of single women who lost out in the race to find a husband - even one with a wooden leg (eg)!
