I think it's unfair to label a sport or all football fans in that way
It would really be quite easy to bring Scudamore down if football fans wanted to. If there was a campaign with a decent amount of support and press coverage to boycott just one match, the PL would roll over and sack him. Just one match. Nobody would want to see the stands empty on the first match of the season. It would be very easy. Fans could just do it - if they wanted to. But they don't want to.
Fans won't boycott their teams because they see them as part of their community. Something passed down by their ancestors. Something akin to a religion.
And all you've done here is confirm that football fans see their afternoon out as more important than whether women are treated with respect by the organisers of the game.
OK, they're prepared to boo him. That's easy - but ineffective. But when it comes to doing something that would involve a bit of sacrifice on their part? Not so much.
