I feel that irrational beliefs are potentially very dangerous for the individuals involved and the world as a whole and I therefore consider myself to be an anti-theist and I try to fight irrationality wherever it goes, but it recently hit home for me and I have no clue how to handle the situation.
When I met my wife, who I've now been married to for only a year and a half, she believed in god but was questioning it. After talking about it with me, she began to acknowledge that there probably isn't a god and she eventually lost her faith. I thought that her religious days were done. The problem is that now, she believes (don't laugh...) that there will someday be a zombie apocalypse. I have tried to talk to her about the more scientific view of the concept of zombies, but just like a theist, she refuses to acknowledge that fearing a zombie apocalypse is completely irrational.
This wouldn't be such a big deal if it weren't for the fact that I am so active in fighting dogmatic thinking. Most of our most cherished discussions have been about religion and why it's so ridiculous. Now, I can't even talk to her about things like that because I just can't take her seriously knowing that she is being hypocritical by denouncing religion because there is no evidence for it but at the same time believing that dead people are going to eat her brains.
She doesn't have a thinkatheist account, so this is really the only place I have any hope of finding help with this situation without embarrassing her. Any help in resolving this situation would be very much appreciated.
