Zo, I still think it ok to attend as a way to "support" your husband.
I know it is annoying to have people always try to convince you with their believes, but with the strong wonderful personality you have I'm sure that won' be a problem, you just need a little patience hehehehehe
It kind of reminds me of the Annual Navy Reunion which I have had to attend (my fiancee is a Lieutenant Commander) for the lat two years. You go and see a thousand people talking and bragging about things you either disagree on or couldn't care less about, but you do your catharsis while coping with them, and two hours afterward you're out of there with your loved one jut enjoying dinner alone in a nice place with no one else around
