What do you think when you come across someone whose religious and political beliefs are the same as those of their parents?

Atheist parents raising atheist kids, conservative parents raising conservative kids. Christians, Muslims, Democrats, Football lovers, whatever it is.
Do you think the beliefs are genetic, do you think that the parents spoonfed the beliefs? Does it disgust you, do you feel neutral about it, does it make you happy?

I was inspired to post this question after checking a new facebook album a friend of mine posted, a local TEA party. One in which he and his parents were involved. I knew that he was a hardcore conservative, as were his parents, for years. I had always kind of felt sad that they forced their beliefs into his head.

Then I turned the view onto my family.
My parents are both secular. They raised 3 lovely Atheist children.
But never in my life have they preached the gospel of Atheism upon us. Never have they taught us the wrongs of Christianity, Islam, Hinduism, so on and so forth. They left us to choose our beliefs.

So I ask again. What’re your thoughts? Do you feel like in these cases, generally the beliefs are forced onto the kids? Do you think it’s almost something genetic?
If you think the parents push it onto their kids, do you think it’s a bad thing?
What’s your story, did you follow in your parents’ footsteps in these ways?
