Do you think schools - and parents - are more or less likely to talk about Qatar and Iran if they watch the game, or if they pretend it's not happening? I think the former. I should think schools talking time out the day to talk about those issues then not screening the games are likely to be few and far between.
I don't know why you are so disparaging about it being "football, innit". I detect a level of classism / implied intellectual superiority in that comment.
Thousands of fans are staging protests at games and on social media, sharing their displeasure at their country's participation. Thousands if not millions more won't watch this tournament as a result. Football magazines are pulling no punches in their criticism.
My primary age DC has been really engaged in conversations about FIFA corruption, human rights abuses, Beckham's work for Qatar, LGBTQ+ rights, whether England should participate and what's happening in Iran, thanks to his love of football. I'm not sure if he'll watch it or not.
Last week an Iranian footballer in the sand football finals made a political gesture supporting women in the protests which was a huge and risky globally-seen move - again my son really took that on board. Football can be a positive platform and show kids how individuals can take a stand even when their govts are doing awful things.
While the professional game is deeply flawed, it's popularity and level of engagement means it can be a brilliant platform for children's learning and understanding.
