You see, being of a certain religion does not automatically means that we are more reasonable than others. I might consider myself to be a little more flexible than others (BTW, if you have questions about us, let me know; I'll be glad to answer but of course, I'm not here to debate or to win religious topic but for reasoning and a nice conversations). As I heard in a movie: "Religion has flaws because men have flaws."
I don't know whether to laugh because I imagine you feeling angry (I'm not being sarcastic though) and stuff or to feel bad about this. I'll make a single question, but of course, this question is not for raising angry comments or anything, just to think about it.
"If you've knew about a doctor who can cure death, and you're getting the treatment to be healed from death, wouldn't you try to tell others as soon as possible about this doctor?" Well, something like this is what we do (Apo. 21:1-4; Mat. 24:14)
About 8am... well, you can tell them to visit on another time to talk about it, since that is the time you use for sleeping. I'm pretty sure that they will understand that.
