It's a particular shame considering that some women's games in England used to get higher crowds than the men's in the period just after WWI.
For instance, a women's game at Goodison in 1920 drew a crowd of around 53,000, with an estimated 10-15,000 more locked out. By comparison, the highest crowd in the men's 1st division that year was some 39,000 at Stamford Bridge. About a year later in 1921 the FA, in what appears to have been a fit of pique and jealousy, banned women from playing - a ban that lasted 50 years.
The Boxing Day a crowd of 53,000 descended on Goodison Park for a women's football match
The women's game has still not fully recovered from that - as can partly be seen from the crowds they get nowadays, which stand in sharp contrast to the pre-ban period.
Imagine that men had been banned from playing football for the 50 years. With no qualified referees allowed to be involved and no stadiums permitted to host men's football, so no more organised leagues, basically only kickaround, amateur games would have been possible.
What state do you think the men's game would have been in, at end of those 50 years? How long do you think it would have taken for the men's game to recover from a total lack of investment or infrastructure for such a long period?
