Because the decisions should be left to those of us playing the sports. Not bystanders trying to impose their own agendas on to activities they don't even participate in.
You can make the decisions, but you can't make the audience (a much larger body of people, who overwhelmingly do not participate in the sport, at least not competitively) agree with (or care about) your decisions or reasoning.
2) why do you think those who care about this don’t care about other issues?
3) this hardly makes the headlines, and wont stay there for long. It doesn’t get outsized attention
But alas. It's easier to spread hate than enact positive change.
