“True, Rashi does say it is assur to go to a stadium. But you have to realize, the program in the stadiums then quite literally consisted of giluy arayos, shvichas dumim, and avodah zarah. Today its just some ball.”
No, please don’t krum op that Rashi. He clearly means partaking in non-Jewish entertainment and sports irrespective of what it entails. If it contained A’Z and Gilui Arayos it would anyway be Asur.
