I suspect there is a wide variety of situations in this matter.
I have met families that somehow convince their offspring to follow their own beliefs, families that pretend to have done so, families that expect/hope to eventually do so, families that reach a mutual understanding of avoiding the subject, and families that hide their beliefs among themselves outright.
What do you feel to be reasonable on this matter?
What do you feel to be significant challenges?
Which priorities apply?
What should we attempt to avoid or pursue?
my relationship with my parents "works" but most of the topics I would want to discuss dont take place at all. It isnt really healthy but its what I've got. Some subjects are understandably off the menu so because they are a bit extreme or taboo but others aren't. A fair number of subjects I wouldnt discuss with anyone in case someone got the wrong idea when I'm trying a sort of intellectual exercise to see another point of view. (It doesnt take a therapist to recognise a connection between the my willingness to entertian extremist ideas and the repressive family life).
For my family, Religion has never been seriously discussed in any depth due to the fact my parents disagree on it, (I'm under the impression that my dad is atheist and my mum is more open but I dont really know any more than that). Politics however is discussed all the time but it is more like "trolling" than anything. Its hard not to join in but I just let them "rant" and humour my dads latest obsession. My mum barely talks to me at all except at dinner and its a conscious effort to talk with her.
The first two years after I came back from university and was living with my parents there were some really big problems. My parents are both homophobic but still profess tolerance in a "dont ask, don't tell" sort of way. As I was coming out as bisexual, dealing with mental problems because of it and begining to take a deeper interest in Marxism, we clashed often. Majors Rows happened about once a month or two months. There have been periodic thaws and clashes since then (about six years ago) but not really as political.
The exception was when I joined the Communist Party last year and disagreements became much more open. After I told them (it was about as much about coming out as a communist as anything), my mum didnt talk to me for a month. (My dad took three days). We live in the same house and You could cut the air with a knife. Actually, that was the first time I ever really did anything my parents thought was wrong knowingly for my own sanity. Even after the first month my mum was suspicious of what she said round me, acted coldly and distant. When I left the party after five months (my own choice-not theirs), things did get easier. when it comes to certian subjects I just get treated as a nerd or with a certian amount of distain and ridicule and my interests are dismissed. Talking on RF is how I deal with it as I dont have to self-censor as much.
I can't really control my parents reactions so I have to look at myself and think about what I can do. If I think its non-negiotable and has to be said, I say it and pick the right time but it can be quite a struggle given that I anticipate a bad reaction. Often its as bad as I think it is but sometimes its ok. Thats true of personal and political stuff. My parents are both extremely resistent to change and inflexible and treat any source of conflict as serious thing. The rest of the time I manage, but I can visibly relax when I have the house for a few hours. It takes about thirty minutes for the effect of being around my parents to wear off. So its far from ideal to say the least and isnt a healthy family relationship.
