Bbarb... You need to put your foot down and tell your husband you can't possibly go, stating the reasons why. I've been in a very similar situation and the whole evening was dreadful. There's nothing worse than trying to be nice to someone you can't stand, it also impacts on your own self esteem as you've compromised your own standards. You've given in to something to please someone else, Making yourself feel unimportant. You need to put yourself first, no doubt you've had a life time of putting others first, now it's your turn.
Is there anyone who still thinks that Israel's actions in Gaza are justifiable?
