An op-ed piece by a contributor to Mishpacha magazine (January ?? 2016 -- not yet online) condemned Jewish attendance at Superbowl parties and compared this cultural "infiltration" into Orthodox Jewish homes as something akin to terrorism. Frankly, I don't think he's right. While watching sports, or attending parties around sports, may involve issues of bitul Torah and secularization, and the commercials may be, at times, too racy to expose our children to, I have to note, that I've known many roshei yeshivos and respected Orthodox rabbis who enjoyed sports on television, including the Superbowl, although I can't say I know any who attended a superbowl party, per se. Some examples: The mashgiach ruchani of RSA, HaRav Shmuel Niman was, before his current illness, a huge sports fan as are his sons. I heard him speak to my congregation and hinted to any Redskins season ticket holders, that he would not turn down an invitation to go to a game. Rabbi Gedaliah Anemer, zt'l, the rounding Rosh HaYeshiva of the Yeshiva of Greater Washington, praised my organization of a synagogue event that drew more than 90 members to a AA baseball game, although he turned down my invitation for him to join us and throw out the first pitch (a privilege we would have earned if we drew 100 attendees). Also, he once sermonized how he once almost blew off attending mincha with a minyan because he was watching an exciting Redskins game on TV (he said, "you know it was a long time ago because they were good then"). He was also known to have corrected a yeshiva student's description of the infield fly rule. The OU in 2014 co-sponsored a kosher Superbowl party, adding kosher entertainment provided by the Nachum Segal Network. Moreover, in Teaneck, NJ, there is a sports bar/restaurant called the Dog House, under the rabbinic supervision of Rabbi Zushe Yosef Blech, Hasgachat Kashrus of Kehillas Bais Ben Zion, Monsey, NY, one of the leading experts in kashrus in the US. In the US, attendance at sporting events has been important in the bonding of Orthodox Jewish fathers and sons (daughters, too), and has been a terrific site for a shiddach date for couples (my daughter and son-in-law had their first date at a Nationals game).
Rabbi Emanuel Feldman, a Mishpacha Magazine columnist and the rabbi emeritus of Congregation Beth Jacob in Atlanta, not to mention the brother of HaRav Aharon Feldman, shlita, Rosh HaYeshiva of Ner Israel, wrote how he attended a Braves World Series game, feeling somewhat guilty that he might be recognized as someone who has better things to do with his time than to surrender to his boy-hood passion for baseball. In an article for Torah from Dixie he retells the story as an entertaining morality tale, also describing the pros and cons of his attendance. At one point in the game, he athletically caught a foul ball which was seen by millions on television, and was the talk of Orthodox Jews around the world, even among those who do not watch television. His catch was cheered by his Atlanta congregants and others in the US. But at his Israeli home in the charedi Har Nof section of Israel, the reaction made him nervous and glad that his children were all married off.
The answer to you is, "it depends" on your hashgafa and your standing in your community. By all means consult your local rabbi or rebbe for guidance.
