Always the same thing.
One side: this is unfair, all girls are suffering because of this, there's a reason girls need their own category, and girls are losing opportunities and places in the girls' competitions in order to let boys have freedom of self expression and use their resources
Other side: ah bless, poor boy, give him what he wants, it's nice to be nice, don't make him sad.
Basically a belief that girls should suffer and lose so that boys never have to deal with boundaries that make them sad.
