> mandating kids to wear masks in schools

There's no evidence that wearing masks prevents contracting Covid (or any other airborne virus). It does a bit toward preventing spreading it if you already have it, but if you already have it, the schools send you home anyway. It's also not as if masks are themselves neutral either - constant mask wearing is associated with higher rates of bacterial pneumonia. Even medical professionals never wore masks all day (until last year), just when they were performing surgery.
