So the gay alums are pissed because they're not accepted at an Orthodox Yeshiva?  They are down with a branch of Judaism which defines half the kids of intermarriage as not-MOT, but can't understand why their same-sex partners aren't welcome at the reunion? 

Look, I'm totally for homosexual equality and gay marriage.  I think my gay Rabbi is great.  But I think it's kind of hypocritical for people who practice Judaism in a way which builds so many walls around the community to get pissed when they find themselves on the other side.  These are the Orthodox community norms, and the Yeshiva alums are well aware of them.  They chose to live a different life when they got out into the wider world.  And in their adult lives, they either continued to attend Orthodox services and left their partners home, or they found people to worship with who accept them as G-d made them, i.e. Conservative or Reform Jews. 

So they want to support the Yeshiva, who says that my house is unclean because I have only one dishwasher, but they want my sympathy because they were welcome at the reunion, but their partners weren't?  Eat a bowl of matzah ball soup at my house, then we can talk, bubbelah.
