Sports are a form if avodah zara where one worships the human body and physical form. It is the opposite of ruchniyus and kedusha where we value the soul and spiritual pursuits.
And yet, just about every yeshiva allows their kids to play some form of sports during recess. And just about every summer camp allows kids to play sports.
I guess practically every yeshiva and camp official are facilitating avoda zara, according to you.
