Had a similar thing happen to me after 9/11. I remember watching TV and being horrified at the events unfolding, but then shortly after, during an elder's sheparding call, they touted that horrible day as something to rejoice in because it could be the start of Armageddon. I wasn't as quick on my feet as you were, though I did take offense at their rejoicing at such horror.
I think they've taken that "raise your head erect, for your deliverence is near" and misintrepreted it to, "rejoice in the trials of others, because 'we told you so' "
