How about I don't have a healthy, loving relationship with either of my parents and I realize that that has made me biased against the parents of other people. I avoid talking to other peoples parents, preferring to talk to their kids instead.
Why do you prefer talking to their kids?
Because I can empathize better with them.
Not everyone is fortunate enough to have good relationships with their parents, and if you don't have a good relationship with your parents then it can be harder to form relationships in adulthood. However, you shouldn't let your biases against your own parents affect the way that you treat other people's parents. Other people's parents aren't necessarily like yours, and you should do your best to be kind towards them and give them the benefit of the doubt.
You may have a point.
You shouldn't assume that everyone's parents are like your own. It would be best to take time to know the parents of another person so that you can understand better the kind of relationship you might like to form with your own.
