I see this with my sister, any time we get into it and I start asking some hard questions, ones she for obvious reasons doesn't want to think about I see her start with the typical objections: These issues are irrelevent, this is just argumentive, its not going anywhere, and the one that makes me the saddest, I don't need to address this stuff, I know what I believe.
Sometimes I feel like a thug, I mean, I can watch it in her face, its right there to see, an almost physical anxiety and panic that grips her when she starts being herded someplace she doesn't want to go.
Defd, I understand man, being asked hard questions is no fun, and that's not just limited to matters of religion. Ask a pregnant mother about what they will do if they find out their fetus is suffering from some dread disease and you will get the same reaction, its just not someplace they want to go if they don't have to.
