Longtime boyfriend and father of children judging my family?

[brunice]

We are 24 and 25yrs old and have a 3yr old and 1 on the way. Me and my dad argue all the time. he blames me for stuff i didn't do and i correct him on it. if i disagree with something my dad or mom say then i speak my mind and we all have a pretty good argument about it. We don't say bless you when each other sneezes...because the devil isn't going to take my soul that way and i'm blessed with or without your help. My boyfriend was raised by family that believes children should be seen and not heard. Even at 25 he is still not allowed to speak his mind to his parents. Pretty much if you weren't raised how he was, then you are disrespecting your parents and you have no manners. You are not supposed to question why things are the way they are and its rude if you do. My parents did not raise me to be a doormat and to speak up if you see something wrong.. not just sit back "cuz yo momma said"(the movie the waterboy). My parents respect the fact that i am now an adult with my own family and i'm entitled to my opinion. his family??? forget about it. How can I get him to accept the fact that we were just raised different and that isn't a bad thing, its just a different thing? In my opinion, whats disrespectful to me might not be to the next girl or next family.
