I went through a similar experience this past Pesach during the Sedar and I have come to the same conlusion: I do not feel there is hope for most people as they feel their beliefs are correct, even though those beliefs are based in irrationality.

Most people feel that it is more important to go with the flow rather than question those belief systems; That we should not hurt anyones feelings, especially when it comes to religion. They just do not get it!
