The greatest Pakistani physicist to ever live, Abdus Salam, was considered a traitor by many of his country men. I think yeezevee can correct if I'm wrong but he's considered a kaffir (since he was Ahmedi).
You husband sounds like a nice, honest guy but has misunderstood a couple of things. This is why, in my opinion, also have to disagree with yeezevee and I think you should continue working on him, especially if you plan on having children.
I think a great deal of the problem is that, aside from me, he gets nothing but reinforcement elsewhere (family, friends, the silly things he reads on the internet, etc). If it weren't for that, I think he might have started to learn a bit more, because he's far more open-minded than many of the other people that were raised like him...
It's tough. If he gets even the vaguest feeling that you're trying to teach him something, he purposefully goes on mental lockdown. But I will try, Descent, thank you.
I don't want the next guy being made fun of for his intellectual dishonesty by ex-Muslims in 20+ years to be my son. I'll try to spare you guys.
